Happy to help! The granularity controls how smooth the pitch shifting is, but it's complex - from the help doc:

Quote
When transposing down, the Pitch Shifter occasionally deletes a snip of audio to preserve tempo. When transposing up, an occasional snip of audio is repeated to preserve tempo. The Pitch Shifter uses a pattern-matching process to locate the best splice points.

When the shifter has to insert or delete pieces of audio to preserve file length, it will not insert or delete snips any smaller than half the Granularity length.

Small Granularity has tighter timing, but can sound nasty on low-pitched or complex signals.

Large Granularity sounds smoother, with possible damage to rhythmic timing.

A granularity of 50 mS works for many types of audio, a compromise between smoothness and rhythmic timing.

The default of 50ms seems to sound best for most things.

That's been added to our bug database, id# 1421.

In Window 11, I can open this file by...

1) Right clicking on Plugs.chm.
2) Selecting "Open with".
3) Then selecting "Microsoft HTML Help Executable".

I cannot recall if I installed the MS HTML Help reader or not.
On my Windows 11 machine the CHM help file opens in the default Windows Help viewer (located at C:\Windows\hh.exe).

These audio plugins can be undone, but like you say they are destructive so once you save and close the song there's no going back. It's always best to have backups of any file though!

I wonder if pitch shifting is a universal process across applications or this granularity concept is unique to the biab plugin method??????
As I understand it, many (though perhaps not all) pitch shifting algorithms work in this way. Some of the more complex ones split the audio into frequency bands, which are separately pitch shifted before being recombined - this can either make the resulting audio better or worse, depending on the source audio and the algorithm...
