Is it possible to convert a selection from stereo to mono?
I have a bunch of audio that I need to run a sequence of operations on, such as stereo->mono, click removal, normalize …
Yes. There’s several ways you can do that. What exactly are you wanting to do?
I get batches of a dozen to a half dozen speeches from a colleague, that are stereo MP3. If he had his mic set up correctly, about all I need to do is convert the stereo to mono, run a filter or two over it (specifically click remove, perhaps compression of about 4:1 if certain individuals are the speakers). Then I normalize the audio, and export the MP3 with constant bit rate of about 56kbps, mono.
After asking the question, I found the “Macros …” menu item and it does about 99% of what I would like to have it do. (so, it pretty much answers my question)
I guess that eventually, I would like to have some code detect where the “intro song” ends and the speech begins, likewise for the ending - but I suppose that I should learn more about XLisp/Nyquist before trying that out. I’m a programmer (not lisp) … but I am very interested in learning.
That’s what I was about to suggest.
That’ll be tricky unless there’s always a gap between the intro song and the start of the speech.

Post back if you find a good, reliable way to do that.
