Have you used BIAB’s audio time-stretch editing inside the Audio Edit window. According to the current Band-in-a-Box User’s Guide, the feature is described like this:

“There are some handy features for stretching or shrinking regions of audio.”

<< Here’s the relevant explanation from the manual, translated into plain English by Chatgpt:

When you:

Select a region of audio
Hold down Ctrl
Click and drag with the mouse

BIAB creates stretch boundaries marked by those orange triangle markers. The area between the markers gets time-compressed or time-expanded.
The manual explains three behaviors:

Click and drag within the selected region
One side gets longer while the other side gets shorter
Useful for moving timing around inside a phrase
Click outside the region and drag into it
The region becomes shorter
Audio is compressed
Click inside the region and drag outside it
The region becomes longer
Audio is stretched

The manual specifically says these tools are useful for:

“quantizing beats”
“correcting mistakes in a recording”

So those orange triangles are essentially transient/stretch anchors that define the area being elastically time-edited. >>

I've never found need to use the feature, but it's there and may help your editing workflow in BIAB.
