That's not really a "bug" is it? If there are 0 samples per second, then there will be no sound.

Normalize the track to -3 or -6 dB before exporting.
Don't expect to get hi-fidelity from GSM6.10

Is there anyway to change that control rate in Nyquist? (control-srate-abs srate beh) [LISP] Evaluate beh with *control-srate* set to sample rate srate. http://www.cs.cmu.edu/~rbd/doc/nyquist/part8.html#index553 Not sure if it really matters, except maybe in waveform to be oscillated creation (migh...

Yes I know. You've already said that.
You have also already said (twice) that you can't hear the piano when you are overdubbing.
We can't help you if you don't respond to what we ask.

There is more than one way to achieve DC offset correction. The two usual methods are: 1) Make the average of positive sample values equal to the inverse of the sum of negative sample values. 2) Limit the frequency range to greater than zero. These two methods do not have identical results, and each...

What is the full and exact location (folder) that you are exporting the WAV files to?
What are the names of the WAV files?
If you go to the export location, can you see your exported files?
If you double click on an exported file, does it play?

Terrific, thanks Kai. Very readable code and nicely commented too. Regarding your note: ;This function follows the code in Table 20-5 of ;1997, Smith, S. "The Scientist and Engineer's Guide to Digital Signal Processing" ;http://www.dspguide.com ;Note: The naming convention in Smith (1997) ...

If your audio track is stereo, convert it to mono before you export (Tracks menu).

Ensure that Audacity is not playing, recording or paused. It must be "stopped" (click on the "Stop" button) before the menu items are available.

Yes you will lose some sound quality, but you will use less if you use the "Sliding Time Scale/Pitch Shift" effect than if you use the ordinary "Change Pitch" effect. The "Sliding Time Scale/Pitch Shift" processes slowly, but it generally produces higher quality results...
