It's similar to your suggestion, but using triangle windows.

You may also be interested in this simple pitch shift algorithm. It is written in C and uses delay lines with overlapping triangular windows. The sound quality is not fantastic, but considering the simplicity of the code it is not bad: https://github.com/audacity/audacity/blob/master/lib-src/libnyqu...

Assuming that you are referring to the "S-Curve" preset in the Adjustable Fade effect, then yes.

no silence offset before file 1 Hope this is clearer. Yes, much clearer :-) This is not a "bug", because it does what it is intended to do, though in my opinion it is a poor design which I hope will be improved at some future time. The problem is that export treats the start of the audio ...

What are you recording and how have you recorded it?
How are you playing back the recording?

Our radio station does a lot of remote broadcasts of music events and festivals, some of which are three to four days in duration. There may be as many as 15 to 25 bands, some of which may play more than once on the same or successive days. We wish to use Audacity to record the performances by each...
