(fmosc (hz-to-step 14500) (mult 6000 (aref s 0))) Which produced a nice looking FM output without visible waveform distortion. Perhaps you can add some improvements to this cod Try this on a mono audio track with a sample rate of 96 kHz: (setf cf 20000) (fmosc (hz-to-step cf) (mult 300 (sum 1 s))) ...

In QjackCtl "Setup", ensure that your UCA 202 device is selected for both input and output (if you click on the ">" next to the selection box it will probably list it by a sensible name). Then start Jack. The main QjackCtl interface should show that Jack is running. Then Open Aud...

I doubt that you will have success trying to "un-mix" a recording with Audacity.
You 'may' have some degree of success with Melodyne (commercial product and quite expensive: http://www.celemony.com/en/start).

Set Audacity to record "1 (mono) channel" in the device toolbar.

Instead of "Change Tempo" you could also try "Truncate Silence" (http://manual.audacityteam.org/o/man/truncate_silence.html) As Truncate Silence only acts on the spaces between words, you may find that the sound quality of the words is better this way so it may be more ineligible...

The earlier versions of Audacity were simpler and I had no problem with them. There's not actually that much difference except that the new version has additional features (that you can ignore). In fact the problem that you are asking about is more to do with Windows than about Audacity. So far wha...

I couldn't hear it myself but perhaps I still need better headphones. Probably do need better headphones ;) The hum on the unprocessed recording is definitely audible. You can also see it if you select some "silence" and then select "Analyze > Plot Spectrum" Untitled.png The thi...

There's a topic here that discusses implementing "silent subliminals" in Nyquist: http://forum.audacityteam.org/viewtopic.php?p=148686#p148686 To the best of my knowledge there is no verifiable or peer reviewed scientific evidence to support the efficacy of "silent subliminals" i...
