As for the superposition/destructive interference etc., that is just how I thought it worked, Sounds like a fair summery of the "Vocal Removal" effect (as described by koz in previous post, or here on the wiki http://wiki.audacityteam.org/wiki/Vocal_Removal ) If you can upload a short sam...

the fact that PCLinuxOS is compiling Audacity with Libsamplerate rather than the Libresample (which SVN would use by default) could be relevant. There are some known crashes in the Play-at-Speed slider at very slow playback speeds if you use Libsamplerate. That's interesting, I usually compile with...

How do you get around the directory designators being different between the Mac and Windows versions? By copying any imported files into the project. Those paths only occur if there are dependencies that are external to the project. Resolving the dependencies avoids the problem (in Audacity 1.3.12,...

These settings in the Equalizer effect will very effectively remove the frequency band from 1 kHz to 2 kHz.
Note the position of the sliders to enable such a strong Eq effect.
Removing a frequency range may not produce the results that you expect.

Then you could use (multichan-expand ...), though it would probably be simpler to use (if (arrayp s)(analyze-stereo s)(analyze-mono s)) By wrapping up the analysis code into a function will remove the need for duplicate code. This is the type of thing that I'm thinking of: (defun analyze (s-in) ; co...

I think Audacity has a bug about AC3, Not exactly - "Audacity" does not support AC3 at all. Importing AC3 files is entirely down to FFmpeg, which is still being actively developed for improved support of some of these more esoteric formats. It is quite probable that FFmpeg may still only ...

So, are there any worthwhile, standalone, inexpensive, (second hand) multichannel digital recorders out there that give pro results? I think an 8 track would do me. It depends what you mean by "inexpensive". For an 8 channel digital recorder you are likely to be looking at a few hundred d...

There are "zoom" buttons available (magnifying glass) (+) Zoom in (-) Zoom out -<->- Zoom to selection >---< Zoom to full project If you have a wheel mouse you can also use Ctrl + Mouse Wheel (probably the fastest way to zoom in and out). If you don't have a wheel mouse you can use Ctrl + ...

For stereo tracks, are you wanting to output data for the combined channels, or "left channel data" / "right channel data"?
