About Band-in-a-Box Audio Files

You can open an audio file by clicking on the [Open+] button on the top toolbar and selecting Open Audio (wav, aif, mp3, m4a, etc.) from the drop-down menu.

Audio files can also be opened by selecting the menu item File | Open Special | Open Audio (WAV, AIFF, M4A, MP4). Once opened, the audio files can be played back at 1/2, 1/4, or 1/8 speed, which is ideal for transcribing or analyzing audio.

When you load an audio file, you can do the following during playback:

• Change the audio tempo to slow down or speed up without changing pitch.
• Press control+[-] for half speed, control+[=] for full speed.
• Loop a section by highlighting an area in the Audio Edit window and clicking [Loop Selected].
• Use the menu item Audio | Set Audio Master (Base) Tempo to ensure that all tempo stretching is based on the correct master tempo.

If MySong.MGU is loaded and an audio file with the same name (e.g., MySong.MP3, MySong.WAV, etc.) exists in the same folder, Band-in-a-Box will automatically load the audio file into the Audio track. This allows third parties to create compact teaching or demo packages by making a pair of MySong.MGU and MySong.MP3. The MGU file provides the chords and structure, while the compressed audio file provides the prerecorded audio, keeping the overall file size small.For example, you could create a trombone teaching set for Band-in-a-Box that includes a song file with the chords and a matching audio trombone track, all packaged in a compact, easy-to-share file size.

Equalize Tempo

If you have an audio file that wasn't recorded at a fixed tempo, you can change so that the tempos in the audio are all at the same. We call this an "equalization" of the tempos.

Click on the [ACW] button on the side toolbar to launch the Audio Chord Wizard.

Then, set bar lines for the whole audio, and press the [Equalize Tempos] button.

[Tip: Press the video button on the Audio Edit window toolbar to see how you can set bar lines. ]

Converting Audio Channels

Easily convert the Audio track from stereo to mono, or vice versa, with the menu item Audio | Edit Audio | Convert Channels (mono/stereo). When you convert the channel, you can choose the percentage of each channel.

 

Audio Offset

The Audio Offset feature lets you synchronize any point in an audio file with bar 1 of a Band-in-a-Box song, so the audio lines up with the rest of the song.

For example, if you have a home recording of a live performance saved as a WAV file (or MP3/AIFF), select the menu item File | Open Special | Open Audio to load it into Band-in-a-Box.

Then open the Audio Edit window, click on the [Nodes] (Volume Automation mode) or the [UT] (UserTrack mode) button . Right-click on the point in the waveform that should correspond to bar 1 and choose Mark this point as Bar 1 of the song from the context menu.

Then, as the song is playing, use the tap tempo feature (the minus key, pressed 4 times in tempo) to set the tempo of the piece.

Your audio file will then start playing at bar 1 of the Band-in-a-Box song in sync with the audio starting at the place you have marked as bar 1, and the bars will be in sync (approximately in sync, they will drift as the tempo of your live performance varies.)  You can put tempo changes on certain bars to keep it perfectly in sync if you want to.

Audio Settings

The Audio Settings dialog allows you to choose the Audio track type (mono or stereo) for the current song or the new songs, and channels (left/right/both) to record the audio.  The dialog can be accessed from the [Audio] button in the Preferences dialog.

Audio Track Type for THIS song: This allows you to choose either mono or stereo for the Audio track in the current song.  If you change this, then you will be asked if you want to convert the existing Audio track after exiting the dialog.
Preferred default track type for new songs: This allows you to choose either mono or stereo for the Audio track of the new songs.
When opening songs, show message if WAV file not found: If the song you are loading has the associated WAV audio file, the audio file will be loaded to the Audio track.  If you enable this option, then when the associated file is not found, an error message will display.  Uncheck this option if you do not want an error message popup when the WAV file is not found.

[Audio Devices]: This will launch the Audio Devices dialog where you can select input and output audio devices.

If Use default device is checked, Band-in-a-Box will use the device currently selected by your operating system (System Preferences > Sound).  Disable this if you want to manually select a device.
The Avoid connecting to low quality input devices option prevents Band-in-a-Box from connecting to low quality input devices, which are usually Bluetooth devices such as AirPods. These devices might reduce audio output quality if input is active.

Import Audio File

Many types of audio files can be opened directly in Band-in-a-Box, but you can also import an audio file into your Band-in-a-Box song. A mono or stereo audio file can be imported to any track, with options to merge with or replace the current audio on that track. Most common audio formats are supported, including WAV, AIFF, MP3, and M4A

To import an audio file, open the Import Audio File dialog by using one of the following methods.

• Click on the [Import] button on the top toolbar and select Import Audio from drop-down menu.
• Choose the menu item File | Import | Import Audio.
• Choose the menu item Audio | Import Audio.
• Drag an audio file from the Finder and drop it anywhere onto the Band-in-a-Box screen.

In the dialog, select the destination track, the point to insert the audio file, and the option to merge or overwrite existing audio in the destination track.

If the audio file contains Acid Loop or Apple® Loop information, the dialog shows an option to set the audio base tempo of the current song to the tempo of the audio file.

AI Stems - Audio Stem Splitter and Transcriber to MIDI

This powerful tool separates a multi-instrument audio file into individual tracks (bass, drums, guitars/piano, vocals, and residual sounds). The separated tracks are then added to your song, allowing you to generate Band-in-a-Box tracks to play along with them. Using advanced AI and machine learning techniques (a process also known as audio source separation), it provides greater flexibility and creative control.

It also includes Audio-to-MIDI transcription, allowing you to convert any separated stem (or the full mix) into MIDI notation. These MIDI transcriptions can be viewed, edited, remixed, or used for learning purposes. For example, you can import vocals from your favorite singer, transcribe a desired instrument part to MIDI, and then use Band-in-a-Box to rearrange or replace the backing tracks, creating a fully personalized mix.

To use these features, open the Stems - AI Audio Stem Splitter and Transcriber to MIDI dialog using one of the following methods.

• Click on the [AI] button on the top toolbar and select AI Stems from the drop-down menu.
• Use the hotkey S T E M S return.
• Select the menu item File | Import | Import Audio File to Separate Tracks using Stem Splitter.
• Select the menu item Audio | Import Audio File to Separate Tracks using Stem Splitter.
• Select the menu item File | Open Special | Open Audio File to Separate Tracks using Stem Splitter.

First, select a file by typing its directory or clicking on the [Choose] button. The file can be an audio file (MP3, M4A, FLAC, WAV, etc.) or a video file (MP4). To split the audio already on the Audio track, click on the [Use Existing Audio Track] button.

Use the Amount to Process setting to choose whether to process the entire song or just a portion. Since creating stems can take some time (typically 10-30 seconds for a full song), selecting a smaller section is useful for previewing the results.

In the Included Audio area, select which stems to add to your song. Typically, you'll want to include all the individual tracks as well as the master track, but you can customize this selection to include only specific tracks if desired.
- Master is the original audio file.
- Bass is the bass part of the song.
- Drums contains drums or percussions.
- Guitar/Piano contains the rhythm section instruments like guitars, keyboards, strings, etc.
- Vocals contains all vocals including harmonies. The vocals won't be separated from each other and will be loaded onto a single track.
- Residual is optional and may be nearly silent or contain faint, non-instrument sounds. When all stems including the residual are imported, the result should sound identical to the original audio file.

The File Options area allows you to select additional options.
- With the Create New Song checkbox, you can choose to add the stems to either a new song or the current song.
- Check the Disable Style option if you don't want the Band-in-a-Box style tracks generated when you play the song, allowing you to hear only the stem tracks.
- The Destination track (first) dropdown allows you to select the destination track for the first stem. The rest will be placed on the next tracks.
- The text entered in the Track labels prefix field will be used for the track names for generated stems.
- If you enable the Preserve WAV files option, WAV files for each track will be saved in the same folder as the original audio file. The audio WAV is always 16 bit 44.1 KHz.
-Enable the Auto-Transcribe ->MIDI option to generate stems and automatically transcribe each one to MIDI when you press OK.

When you are ready, press [OK - Generate Stems]. For a full 3-minute song, the process may take 10-45 seconds to complete. The routines use multiple CPU cores, so it will be faster on fast machines with higher performance and more cores. If the auto-transcription is enabled, this button will change to [OK - Generate Stems & Transcription], and pressing it will separate the file into individual tracks and automatically transcribe each one to MIDI.

Once the stems are generated, they will be added to your song and will appear in the Mixer. You’ll see a Master track, which is the original audio file, unchanged. Normally, you want to mute this track because you will be hearing the same thing on individual tracks. It is set to mute (red) by default.

Now you can play these tracks as a group, remix them, or mute/solo any individual track. The possibilities for creative fun are endless!

To play these tracks in sync with the Band-in-a-Box style tracks, set the song to the same tempo as the source file. This ensures proper timing and seamless integration. If the source file contains tempo variations open the Audio Chord Wizard, mark the bar lines, and let it determine the chords of the song. Once the song is synced and the chords are entered, you can select RealTracks, MIDI SuperTracks, Loops, etc. or change a style to play along with any or all of your tracks.

When you save a song, the stem tracks will be saved as audio files using the song file name followed by the track name. For example, if you save the song as Sunshine.mgu, the stem tracks will be saved as Sunshine-bass.wav, Sunshine-drums.wav, and so on.

AI Notes - Audio Transcriber and Stem Splitter

The amazing “AI-Notes” feature transcribes polyphonic audio to MIDI, allowing it to be viewed in notation or played as MIDI. It can transcribe an entire audio file (all pitched instruments and all drums), or it can isolate and transcribe individual instruments (drums, bass, guitars/piano, and vocals). It uses an advanced AI neural network to produce highly accurate results that sound exceptionally musical when played. For example, load your favorite pop song and generate transcriptions for its instruments (bass, drums, guitars/pianos, vocals), which you can play on their own or along with the audio of the song. This is an excellent way to learn songs, as you can visually follow the parts as they play on the piano keyboard or guitar fretboard. You can also use this feature together with the “AI-Stems” feature to split the original audio into separate tracks.

To use it, click on the [AI] button and select AI-Notes from the drop-down menu, or use the hotkeys N O T E S return or S S 1 6 return to open the Notes - AI Audio Transcriber and Stem Splitter dialog. Then, select a track containing audio that you want to process, choose the instrument(s) to split and/or transcribe, specify the destination track(s) for the MIDI output, and press OK.

Input Audio from Track: Transcription or stem split processes use the existing audio in the track selected here.
[Import]: This lets you select an audio file to import to the selected track.
[New Song]: This clears the current song, allowing you to open a new audio file to a new song using the [Import] button.
Process Whole Track / Process Partial Track: Choose whether to process the entire song or only a portion. Because transcription can take time (up to two minutes for a three-minute song), selecting a smaller section speeds up processing.
Offset from start: Specify the location where the transcription begins.
Duration: Set the length of audio to process from the start location
Disable Style: Check this if you don’t want the style to play along with the audio.
One Track / Master + 4 Tracks: Choose to output transcriptions and/or stems for a single instrument or multiple instruments.
Audio Stem(s): Select this to generate stems. You should also select a destination track for the generated stems.
Transcribe to MIDI: Select this to transcribe audio in the selected track to MIDI. You should also choose a destination track for that MIDI output.
Notation Type: Select a type to assign the correct channel, patch, and notation display for the output track.

Stem Splitter Player

The Stem Splitter Player allows you to play stems without triggering the Band-in-a-Box style tracks. It also includes Audio-to-MIDI transcription, enabling you to convert stem tracks into MIDI notation for viewing, remixing, or learning purposes. Explore your stems and MIDI transcriptions for flexible music production and creative experimentation!

To launch it, select the menu item File | Open Special | Open Stem Splitter Player.

The menu bar contains following menus:

Open to browse and select an audio file (.wav/.mp3/.flac/.ogg/.wma /.m4a/.mp4) to load. Stems for options to split songs into stems. Transcription for options to transcribe songs to MIDI notation. A powerful transcription engine converts pitched instruments or drums into MIDI format, offering endless possibilities for remixing, learning, and music production. Library to manage your song library.You can also drag and drop one or multiple songs directly onto the Library panel to instantly add them to your collection. Settings to configure application preferences and behavior. Enable the Auto-Split After Open setting to automatically begin splitting a file into stems immediately after opening it. If Auto-Transcribe After Split is enabled, all stems are automatically transcribed after the splitting process is completed. The Output option includes stem format selection (.wav, .mp3, .ogg, etc.), residual stem transcription, and subfolder creation. The Reset Settings option quickly returns all settings to their default state.

The toolbar provides quick access to essential functions for managing and processing audio. Use [Split] to separate the current song into individual stems (vocals, bass, drums, guitar/piano, and residual) based on enabled tracks. [Transcribe] transcribes audio to MIDI notation, processing the source file if no stems exist or all enabled stems if available. [Start Time] lets you specify the exact point in the file to begin processing, and [Length] sets the duration to process from the start position; both values automatically update when selecting a region on the waveform.

The interactive waveform display shows your source audio file with precise time references. The timeline provides a visual representation of your audio and links directly to the Start and Length parameters. You can navigate a large file effortlessly with zoom and scroll buttons. You can select a region of your file by clicking and dragging. This updates the Start and Length values automatically, making it easy to process only the selected region.

Just below the toolbar buttons is the transport control area, which includes standard playback controls such as Play, Stop, Pause, Replay, and a progress bar for navigating through the audio. This area allows you to control playback and monitor your position  in real time.

The track table displays the source audio file directory along with transcription, mute, solo, and volume controls for the source file and all five stems. It provides quick access to playback control, stem selection, and individual track settings. Each track includes a transcription button (eighth note icon) that, when clicked, generates a transcription for that track (stem or master). When the button turns blue, indicating that a transcription exists, you can drag it to export the MIDI file directly to your desired location.
The Library panel provides a centralized view of all songs in your library. To add songs to your library, use the Library menu or drag and drop files directly onto the panel.

Load an audio file by using the File menu or by dragging and dropping a file onto the track table, adjust the settings (start position, length, and stem selection), and click on the [Split] button to separate the file into stems. Then click on the [Transcribe] button to convert all stems into MIDI. Whenever all stems are transcribed, the program also generates a multi-stem combined transcription, which merges all individual stem transcriptions into a single master transcription. If you enable the “Auto-Split after Open” and “Auto-Transcribe after Split” in the Settings menu, simply loading a file automatically performs the full split and transcription process for a more seamless workflow.

Record Audio

You can record vocal or instrument performance to your song

To get started, press the [Record] button on the top toolbar.

The [Audio Options] button will open the Audio Settings dialog, where you can choose the Audio track type (mono or stereo) for the current song or the new songs, and channels (left/right/both) to record the audio.

The [Set Recording Levels] will launch System Preferences > Sound where you can select a recording device and recording levels for that device.

Set the start point for the recording.

You can record from the start of the song, somewhere in the middle, or punch in by choosing a bar and chorus # to start recording.

Select the destination track.

Audio can be recorded to the Audio or a Utility track.

Select the destination track for recording MIDI.

If you also want to record MIDI at the same time, choose the destination track with the “Record MIDI to” option.

Select the punch-in recording option.

Punch-in audio recording allows you to punch-in record or overdub a section of audio. You can select a section to punch-in by highlighting it in the Audio Edit window. You can also hear the existing audio part when you are overdubbing. This is automatic.

Select the overdub underlying audio option.

If you have previously recorded audio on the track, and want to overdub (to add a harmony for example), then you should select the “Overdub underlying Audio.”  It is not essential to select it at this point, since you will get another chance at the end of the recording. Note that the Audio track will not play during record, so you’d have to sing the harmony without hearing the original audio part.

Set the track type (stereo/mono) for recording.

The dialog displays the mono/stereo status of the recording, but if you want to change it, press [Audio Options] button.

Test the recording level with VU Meters.

The meters show the average strength of the signal, with a dB scale, and a clip indicator. Clipping indicates that the signal has overloaded and will sound distorted (clipped). The green area represents normal levels, while red indicates an overload. Ideally, the sounds should remain in the green and avoid the red altogether. Unlike analog recording, where it’s good to get a “hot” high signal, digital recordings need to absolutely avoid high levels since any overload of the signal will result in clipping and a ruined.

Press [Record].

Audio recording begins. If you have set the “Leave VU Meter while recording” option, then the VU Meter will open and display during recording so you can monitor the VU meters.

Press the [Stop] toolbar button or press the [Esc] key.

You will then see the Audio Recorded - Keep Take? dialog.

Copy 1st chorus to whole song: If you have recorded only the first chorus, you can choose the option to copy that to the whole song.  This will fill up the whole song with the audio by repeating it as many times as necessary.
Overdub underlying Audio: If this is enabled, any existing data in the track will be merged with the new recording.
Retain audio past last recorded: If this is unchecked, any audio that follows the end of the current take (i.e. recorded from a previous recording) will be erased.

Press the [OK - Keep Take] button if you are happy with the recording, and the audio will be added to the Audio track.  You can listen to the result by pressing the [Play] button on the toolbar.  If you are not happy with the results, select the menu item Edit | Undo Record Audio and you will be back to where you were prior to the recording.  You can also reopen the Record Audio dialog and press the [Take Again] button to cancel the recording.

Your recording will be saved as a .WAV file when you save the song, using the same name as the song. For example, if you record audio to the Audio track and save the song as MySong.MGU, the recorded audio will be saved as MySong.WAV. If you record audio to the Utility #1 track and save the song as MySong.MGU, the recorded audio will be saved as MySong #1.WAV.

Audio Input Monitoring

This is like "Audio Thru" and it routes incoming audio to Audio Out.

To use this feature, you need to arm the track that you are recording to. Right-click on the track button in the Mixer and select the Arm Track for Audio Input Monitoring menu item, or right-click on the VU meters and select Arm Track from the menu.

The VU meters right-click menu has options to select an audio input. For example, if your audio interface has two inputs (right/left) and you want to record from a microphone plugged into the right input, select the Mono Right to Stereo menu item.

When the track is armed, blue borders are drawn around the VU meters. You can now monitor audio input along with the effects that you select on that track. For example, if you want to add a tremolo effect to your recording, right-click on the first slot in the Mixer, select Choose Plugin from the menu, and select a tremolo effect. Now, when you sing or play an instrument though the microphone, you will see it on the VU meters and you will hear it along with the tremolo effect.

Generating Synthetic Vocal

Your Melody or Soloist track with lyrics can be rendered to a vocal audio track, with built-in support for the popular online vocal synth “Sinsy.”

[Note: An internet connection is required to use this feature.]

To uses this feature, you should first enter melodies and note-based lyrics to the Melody or Soloist track.  If no lyrics are present, you can still generate a vocal synth using the syllable of your choice (e.g. la la la).

The Vocal Synth generation can be accessed from the menu item Edit | Lyrics | Vocal Synth.

This feature has two modes – manual mode and automatic mode. In manual mode, Band-in-a-Box creates a Sound.XML file, which you upload to the Sinsy server. After Sinsy generates the synthetic vocal audio file, you import it back into Band-in-a-Box. Automatic mode is normally used because it handles the entire process for you. When automatic mode is selected, the Generate Synthetic Vocal dialog opens.

Language: The choice is English or Japanese.  Select English unless your lyrics are entered in Japanese.
Vocalist: Choose one of the female or male vocalists.  If the language is set to English, you can only select an English singer.
Gender Parameters: You can adjust the gender of the voice in a range from -0.8 to +0.8.  Higher values are more masculine.  The default is 0.55.
Vibrato Intensity: This controls the amount of vibrato in the voice.  The range is from 0 to 2.  The default is 1.
Pitch Shifting: This setting will shift pitch in semitones.  The range is from -24 to +24.  A setting of -12 would be down one octave.  The default is 0.
For Melody notes with no lyrics use: If the track does not include lyrics, you can enter a syllable (.e.g. la) to use for notes with no lyrics. (Note: If you select a Japanese vocalist, you need to enter a Japanese syllable.)
When you press [OK], your song will be sent automatically to the Sinsy server and will be rendered to a vocal synth.  This may take a few minutes. When the vocal synth has been generated, press the [Play] toolbar button to hear the vocal synth singing your song!

Editing the Audio File - Audio Edit Window

The Audio Edit window shows a digital waveform and allows you to select, preview, or edit audio data on any track.  

It is opened with the [Audio Edit] button on the side toolbar or the menu item Audio | Audio Edit Window

[Note: When you edit audio data, it will be saved in a WAV file, not in an MGU/SGU file. For example, if you edit the Audio track in a song called MySong.MGU, the Audio track will be saved in MySong.WAV. For the tracks other than the Audio track, the track names will be added to the WAV files, e.g., MySong Melody.WAV, MySong Bass.WAV, MySong #1.WAV (for the Utility#1 track), etc.]

The window displays stereo WAV files as two separate tracks.

The ruler below the toolbar indicates bars and beats, with a full height vertical division for each bar and a short vertical line for each beat or quarter note. Bars with part markers also include the A or B part marker letter with the bar number (1a, 9b). The decibel (dB) scale is shown at the right of the window.

Use the [-] and [+] buttons at the bottom-right corner to zoom in or out horizontally. You can also zoom using the mouse wheel.

A region of the audio can be selected by clicking and dragging the mouse. To select a large region, you can click on the starting point and shift+click on the end point. To expand or reduce the selection, hold down the shift key while clicking on the desired new boundary. The selection can be played using the [Loop Selected] button.

There are some handy features for stretching or shrinking regions of audio. To use these features, select a region of audio, then click and drag while holding down the command key. Clicking within the region and dragging to somewhere else within the region will stretch both halves of the region (one will become longer, and the other will become shorter). Clicking outside the region and dragging to somewhere in the region will shorten the region. Clicking within the region and dragging to somewhere outside the region will lengthen the region. These features can be useful for quantizing beats or correcting mistakes in a recording.

The window has four modes – Standard mode, Volume Automation mode, Audio Chord Wizard mode, and UserTracks mode. Volume Automation mode allows fine volume control of any track for fades, crescendos, mutes, etc. Audio Chord Wizard mode allows you to create and edit bar line markers for chord interpretation. UserTracks mode is used to create and edit bar line markers for your UserTracks files.

The [Whole Track] button zooms out as far as possible to show the entire audio track.

The [Samples] button zooms in to the finest level possible. At this level, you will see interpolation between the sample points. This uses band-limited interpolation, which represents how the waveform will sound when converted from digital to analog.

The Snap setting allows you to select audio by snapping to a 16th note (or a triplet in Swing styles). A section of the waveform can be selected by clicking and dragging the mouse over a region. To expand or reduce the selection, hold down the shift key while clicking on the new boundary.

The [Loop Selected] button plays the selected region.

The [Select All] button selects the whole track, which is useful for applying built-in audio plugins.

The [Edit] button opens a menu for various editing commands. These commands apply to the selected region, or to the entire track if nothing is selected.

The [Edit] button opens a menu for various editing commands. These commands apply to the selected region, or to the entire track if nothing is selected.

Silence: Erases the audio. The hotkey is delete. Amplify: Increases or decreases the audio volume by a specified number of decibels. Positive values make the audio louder; negative values make it quieter. Normalize: Adjusts the audio level so that the loudest peak matches the specified decibel value. For example, if you choose –6 dB and the current loudest point is –8 dB, the audio will be increased by +2 dB. Fade In: Gradually increases the volume from silence to full level. You can adjust the fade curve in the Audio Edit Settings dialog. Fade Out: Gradually decreases the volume from full level to silence. You can adjust the fade curve in the Audio Edit Settings dialog. Cut: Cuts the selected audio. The hotkey is command+X. Copy:Copies the selected audio to the clipboard. The hotkey is command+C. Paste: Pastes the copied audio at the current location, replacing the existing audio. The hotkey is command+V. Paste (Mix): Mixes the copied audio with the existing audio instead of overwriting it. You can specify the percentage of the original audio to keep and the pasted audio to mix in.The hotkey is command+shift+V. Paste (Insert): Inserts the audio from the clipboard at the current location instead of overwriting. Audio to the right of the insertion point is shifted to make room. Insert Silence: Inserts silence at the current cursor position. The inserted silence has the same duration as the selected region. Delete: Deletes the selected audio. The hotkey is shift+delete. Convert Channel: Converts between stereo and mono. If the audio is stereo, it is converted to mono; if it is mono, it is converted to stereo. You can specify the percentage of the left and right channels to include. Transpose: Transposes the audio by a specified number of cents. Harmonize: Adds harmonies to audio. Fix Tuning: Automatically corrects tuning based on the song key. For example, in the key of C, if a C# is detected, it will be corrected to C or D depending on which is closer. Fix "Sour" Notes: Automatically corrects notes in polyphonic audio. When multiple notes are played at once in a chord, this feature can adjust certain notes so they do not clash with the chord progression or other tracks. In the dialog, you can select one of several auto-fix rules.   Process MIDI: If enabled, any MIDI notes on the track are processed as well. Notes within the selected region are modified according to the selected rule. Sensitivity Level: Increasing this level causes weaker notes to be detected. Decreasing it causes weaker notes to be ignored and left unaffected by the auto-fix. Transient Level: Increasing this level makes transients (e.g., plucks or drum hits) more prominent. Decreasing it makes transients less prominent. Smoothing ms: Specifies the time, in milliseconds, over which notes change pitch. Increase this for instruments that sound better with slower pitch transitions, such as vocals or pedal steel. Decrease it for more rigid-sounding instruments like piano. Pitch Correction: Corrects the tuning of detected notes. For example, if one guitar string is slightly out of tune, notes played on that string can be pitch-corrected. Generate: Generates RealTracks. Settings: Opens options for customizing the appearance of the Audio Edit window and the Tracks window.   Auto cross-fade regions: When a region of audio is modified or replaced, the beginning and ending of the region are cross-faded with the existing audio to make a smooth transition. This applies to Cut, Paste, Silence, Amplify, and Normalize. Default fade type: Choose the type of curve used for the automatic/manual cross-fading. “S-Curve” works well in most situations and is best for very short fade durations, as it does not introduce noise. Default duration in samples for cross-fades: This is the number of samples used for audio cross-fading. This duration will be shortened automatically when processing very short regions of audio. Synchronize insert/delete edits with MIDI on track: If enabled, MIDI on the same track will be shifted when inserting or deleting regions of audio, keeping the MIDI and audio in sync. Mouse wheel zooms to edit cursor instead of mouse pointer: If enabled, the mouse wheel will zoom to the edit cursor instead of the mouse pointer. Center screen to edit cursor when zooming: If enabled, the edit cursor will scroll to the center of the window when zooming with the mouse wheel. This applies only if “Mouse wheel zooms to edit cursor instead of mouse pointer” is enabled. Delete decompressed WAV files when loading songs: If your song has compressed audio tracks (e.g., MySong.M4A for MySong.SGU), disabling this setting will keep a copy of the decompressed WAV file that is created. This allows faster song loading the next time. Draw interpolation: If enabled, the curved lines will be drawn between sample points to represent the sound more realistically. Interpolation quality: This sets the accuracy of the interpolation drawing. Enable ‘Edit Phrases and Loops’ Mode in Tracks Window: This is a specialized Tracks Window mode where boxes are drawn for RealTracks phrase segments. These phrases can be edited in a few ways:  Copy and Paste to different locations on the same track, delete by pressing the DEL key, move by dragging the top of the box, or change the duration and starting location by dragging the sides of the box.

Following hotkeys are available.

• home moves the cursor to the beginning of a track.
• end moves the cursor to the end of a track.
• shift+home moves the left cursor of the selected region to the beginning of a track. If no region is selected, this will select a region from the cursor to the beginning of a track.
• shift+end moves the right cursor to the end of a track. If no region is selected, this will select a region from the cursor to the end of a track.
• command+A selects the whole track.
• command+C copies the selected region of audio to the clipboard.
• command+X cuts the selected region of audio.
• command+V pastes the copied audio to the current location and overwrites the existing audio.
• command+shift+V pastes the copied audio and merges it with the existing audio instead of overwriting it.
• delete erases the selected region of audio.
• shift+delete deletes the selected region of audio.

Volume Automation

Node-based volume automation allows fine volume control of any track for fades, crescendos, mutes, etc.

We’ve created over 170 original songs sung by a variety of very talented singers in a variety of genres. They can be played in Band-in-a-Box and are great for experimenting with different styles. The songs are saved in the Artist Performance Set 11 to Artist Performance Set 18 subfolders in Band-in-a-Box/Artist Performance Sets.

Let’s load a song called “Emmaline 100 country male C _goldrsh.MGU” from the Applications/Band-in-a-Box/Artist Performance Sets/Artist Performance Set 12 - Songs with Vocals volume 2 folder. This song has great leading and background vocals, but when you play the song, you may notice that the background vocal is too loud.

Open the Audio Edit window and see the background vocal track. In bars 21–27, you may notice that the first half is slightly louder than the second half. While you could adjust the volume in the Mixer window, that would change the level for the entire section. A better approach is to use Volume Automation for more precise control.

Switch to Volume Automation mode. You’ll see a blue line on the track. Click anywhere on the line to add a node, which acts as an anchor. Add more nodes as needed and move them up or down—the blue line will be drawn between the nodes. The position of the blue line at any point determines the volume change in decibels for that moment. When you play the song, the background vocal will be balanced between the two sections. You could have the vocal start off quieter and have it gradually become louder.

Analyzing Chords in Audio - Audio Chord Wizard

You can import chords from an audio file using the Audio Chord Wizard. It analyzes audio files (WAV, MP3, M4A, etc.) and imports the results into Band-in-a-Box. It detects tempo, bar lines, and chord changes, making it easy to turn your favorite audio files into playable Band-in-a-Box songs.

After loading an audio file to your song, launch the Audio Chord Wizard with the [ACW] button on the side toolbar, the hotkey S S 1 4 return, or menu items Audio | Audio Chord Wizardor File | Open Audio with Chords (WAV, WMA, MP3, WMV, CDA).

[Note:  The Audio Chord Wizard uses a special multi-view layout, with the Chord Sheet on top and the Audio Edit window on the bottom.]

The first task is to locate bar lines in the audio so that the Audio Chord Wizard can detect chords accurately and the audio will play in sync with the Band-in-a-Box song.

You can define bar lines using the [Add Bar Line] button on the toolbar or by pressing the L key. A bar line will be placed at the audio edit cursor, or at the playback cursor if the song is currently playing.

When you start entering bar lines, the program automatically sets the tempo of the song to the tempo of the first bar of the audio.

Once the tempo of the first bar is set, the program automatically moves the location of the first bar of audio over so that the visual space of the count-in bars is visible.

After you've added the bar lines, IF you adjust the first or second bar and the tempo of the first bar changes accordingly, the program automatically changes the tempo of the song to match.

The [Add/Delete Bar Lines]button provides options to add bar lines based on your song structure or tempo. You can also delete all existing bar lines or only those within a highlighted region.

If the Auto Marking option is enabled, the wizard will automatically add and arrange bar lines based on the ones you’ve added manually. By default, auto-generated bar lines appear in light blue, while user-defined bar lines appear in purple.(Tip: You can customize these colors in the Display and Chord Sheet Settings dialog, accessible by clicking the gear icon on the Chord Sheet toolbar.)

If the Auto Analysis option is enabled, the wizard re-analyzes the chords in the audio whenever you add or move a bar line, or when you edit the audio data.  Keep this setting disabled if you prefer to set all bar lines first (i.e. establishing tempo), and then analyze the chords when you are done.

Bar lines can be moved with the mouse.  Just click and drag the thumb control at the bottom.  If you move an “auto” bar line, it will become a “user” bar line. 

You can also right-click on the thumb control to get a context menu with options to switch a marker type (“user” or “auto”), delete the bar line, or set the time signature for the bar.  The menu also shows you the tempo of the bar, based on the time signature of the bar and the position of the next bar line.

Use the [Analyze] button to detect chords in the audio and write them into the Chord Sheet. You don’t need to do this if the “Auto Analysis” option is enabled, but it can be useful if you’ve erased or modified chords in the Chord Sheet.

When you add or move bar lines, the wizard automatically generates a tempo map so your song stays in sync with the audio.
Any changes made in Audio Chord Wizard mode can be undone.

On the Chord Sheet, you will see that the Audio Chord Wizard has entered the chords and the tempo map.

If you enable the Transcribe MIDI to Track option, the wizard will send the transcribed MIDI notes to the track for further analysis (in the Piano Roll or Notation window). Note that this provides a “snapshot” view of the pitches every 8th note and is not intended for full polyphonic transcription

The [Equalize Tempos] removes tempo changes by stretching regions of audio so that the tempos are all equal.

The [Chord Settings] button allows you to customize the chord analysis settings.
Song Key: Choose the key in which to look for chords.  For example, if the song key is set to G major, the wizard will search for chords in the key of G major.  These G major chords are further specified by the Chord Preset.
Chord Preset: Choose which set of chords to look for, from the chosen key.
Pre-tune audio: Auto-tune the track to a reference of A440 before performing the chord analysis.  This is useful for songs that were recorded slightly out of tune.
Minimum chord duration 1 bar: This forces the wizard to choose only 1 chord per bar (i.e. no half-bar chords).

Audio Harmonies

The audio harmonies include following features.
- Harmonizing the audio with up to 4 voices.
- Correcting out-of-tune notes.
- Transcribing the audio to notation.

First, import an audio file or open a Band-in-a-Box song file with audio.  Then, go to the menu Audio or Harmony, and select Audio Harmonies, Pitch Tracking, Fix Tuning (Audio Edit).

This will open the Audio Edit window and the Audio Harmony dialog.

[Tip: If the Audio Edit window is already open, press the [Edit] button on its toolbar and select Harmonize from the drop-down menu. ]

Choose one of the 3 harmonizing modes.

• The “Chords” mode will harmonize the audio based on the chords in your song.  Choose a type of harmony from the “Harmony type” option.  Choose either the intelligent mode, which allows you to select the number of voices and other options, or one of the harmony presets.  Then, set the volume and the stereo balance of each voice in the harmony. When you select the intelligent mode, you can also use the “Melody Double” option to make one of the harmony voices double the original melody.  For the 2-part harmony, you can make the harmony voice 3rds or 6ths above/below the original melody depending on the “Voice above” setting or a combination of 3rds and 6ths with the “Duet Voicing” setting.
• The “MIDI” mode will add voices to the audio, based on melodies in the source track.  You can choose the number of voices (up to 4 voices), and the volume and the stereo balance of each voice.
• The “Fix Tuning” mode will analyze the track and corrects out-of-tune notes in the selected region according to the key of your song.  Normally, you do not want to keep out-of-tune notes after the fix tuning is done, but you can mix the original voice with the fixed one by moving the volume slider for “Original Melody” to the right.

Source track is the track that the selected harmonizing mode will apply to.

If Output to separate tracks is unchecked, harmony voices will be written into the source track and merged with the existing audio in that track. You can also set the volume and stereo balance for each harmony voice. If you check this option, harmony voices will be written into other tracks that you select with the Destination track option. After harmony voices are generated, you can use the Mixer to control volume, panning, reverb, and tone, or add effects for each voice.

You can enable the Transcribe option for the source track and/or harmony voices. Note that the audio in the source track should be monophonic (e.g., vocal, saxophone).
