I use BB 2022 with the latest update on Mac & Win!
To imitate the issue,
1: Use a BB session with an Audio track or create one.
2: Convert Audio track to mp3 (I do this outside BiaB), and replace the Wav Audio file,(delete wav file after conversion).
3: Open the session with the mp3 audio with BB 2022, it will convert the audio to wav but it will not create a wav file with the same name at the song directory.
4. Create a new folder and "save as" the session as a new file, it save only the .mgu file and no audio at all.
5: Open the Song/session with the mp3 with BB 2020, and it will create automatically a wav file in the song directory (folder), for use in the next time that you will open the song.
Thanks!
<<"For size reasons we use to convert the .wav audio file of a song to mp3 files for BiaB Win, and Mpeg4 for BiaB Mac. Then when you open the session BB was automatically creating a single file with the same name, as .wav so it will open faster with no conversion the next time, because BB was and it still uses .wav files, (there was no ability to have more than one audio file before BB2021).">>
I may can provide you some information that will resolve your issue and streamline your process.
First, not having the ability to have more than one audio file before 2021 is incorrect. There can be more than one audio track in BIAB. In fact, 10 audio files is no problem for BIAB with both Win and Mac versions all the way back to Win/Mac versions 2015.
While the BIAB Mixer has only one Audio Track, that track can be used over and over as many times as needed. This is because of all the different media formats that can be loaded by a BIAB Mixer Legacy Track. The BIAB Mixer Tracks can load Midi, SuperMidi, Loops, RealTracks or recorded Audio. Prior to 2021 and the introduction of Utility Tracks, BIAB only had the seven Legacy Tracks (Bass,Piano,Drums,Guitar,Strings,Melody,Soloist and Audio ) BIAB uses a feature called the Artist Performance File to convert and move audio files onto the other Legacy Tracks. The Artist Performance File also saves the audio and name's the audio file with the song project.
So as to not take this thread off topic about the past, only to explain that this process is still available and even with Utility Tracks available, audio files can still be imported or recorded into the BIAB Mixer, loaded and saved to open every time the BIAB SGU file is opened in the future. PG Music has a folder with over 50 demos recorded with vocals and backing tracks demonstrating this feature. Yes, they use the Utility Tracks but it isn't necessary.
But to your issue:
01. Create or import an audio track on any BIAB Mixer track 02. Save the project into any known location 03. Right Click with mouse on the track with audio 04. From the drop down menu, select Track Actions 05. From the Track Actions drop down menu, select Save Track as Performance File (wav\m4a)
This action saves the audio into the same folder as the SGU project, names the file and BIAB will open with that file loaded and synced on that track whenever the file is opened in the future.
PG Music has chosen to change the compressed format from MP3 to the M4a format but that can be converted to MP3 if desired.
