I have an audio recording in which 1 kHz tones divide its segments. There are so many segments that it would take a while to use Audacity to manually split the file. Is there an automatic plug-in or program to do this?

This is actually possible using Audacity's Beat Finder analysis plug-in when combined with a bandpass filter.
(reson s 1000 1 1)
into the box.1000
with the frequency you got from Step 2.0
Hmm, how's your lisp? Audacity multi-export, as described http://wiki.audacityteam.org/wiki/Splitting_recordings_into_separate_tracks does what you want, given appropriate labels.
Seems it'd be possible to combine the auto-label-silence script from there (named SilenceMarker.ny) with the simple spectral processing example from http://audacity-forum.de/download/edgar/nyquist/nyquist-doc/examples/rbd/03-fft-tutorial.htm to do labeling based on freq. If I had to do it, I'd give it a try, but lisp isn't one of my languages.
It may not be a practical suggestion, but find the binary code for that tone, and split by it. – soandos – 2011-06-09T17:20:06.753
