You're asking about the audio track in Biab? That answer is no. Not to be too obvious but if you're asking about simply changing tempos in a regular Biab song, it will regenerate the RT's as audio no problem.
If you have prerecorded audio tracks you can pitch shift or stretch them in Real Band. You don't want to go too far with that but if the original track is 100 BPM and you need 108 or 90 that should be no problem.
I think the procedure would be to start with a new project in RB. Say you want 108. Set the tempo to 108 then import your audio track that's at 100. Once imported you open it in the Audio Edit window and stretch it to 108. Now you can start recording or generating new Biab tracks at 108. If you have some Biab tracks already done at 108, just import those in, no need to create them again.
RB has 48 tracks to play with so you have plenty of room to experiment. The key though is to make sure you start the project fresh with whatever tempo you want.
There is other software as well that can change length without changing pitch, or pitch without changing time. Bob is correct and trying to shift more than a little can introduce artifacts (unwanted sounds).
BIAB 2025 Win Audiophile. Software: Studio One 7 Pro, Swam horns, Acoustica-7, Notion 6, Song Master Pro, Win 11 Home. Hardware: Intel i9, 32 Gb; Roland Integra-7, Presonus 192 & Faderport 8, Royer 121, Adam Sub8 & Neumann 120 monitors.
Both Time Stretch and Pitch Shift are available in RB. Select the desired regions of the tracks. You can do multiple tracks or single tracks, and the whole track or just a section. The key is to select the correct section(s).
Then Right-Click and use the option shown in the first image. Then further options in the second image will then appear in a popup.
Pay attention to which check boxes are active and how you set the desired changes.
To Time Stretch without Pitch Shifting, uncheck Pitch Shift, and use the Tempo boxes above to adjust the speed. The Percentage will change and adjust, but for Tempo these are just informational.
This combo tool allows adjusting Tempo, Pitch or both .. long as you pay attention to the available options. If I recall correctly, it now uses the same algorithm as the native BiaB/RB generation tool (Elastique) so it is pretty good.
I do not work here, but the benefits are still awesome Make your sound your own!
Thanks all! Very cool! Yes, Elastique is really good. It amazes me every time I hear it. I’ve got a rather large tempo change, so I think I’ll go with re-recording the track. JZ
I have never really tried time stretching software but I can't imagine that it wouldn't sound funky on anything more then a small adjustment. I could-be wrong. WSS
