Read my post again.
Processing multiple tracks simultaneously is perfectly do-able.

i have tried hooking up a 2to1 rca (red and white to single aux) from my mixdeck to my computer The only connection between the mixdeck and the computer should be the USB connection. Have another look at the mixdeck set-up instructions - you have probably got something wrong there. Also, some of th...

The "hiss" is not "feedback". "Feedback" is when output sound (for example from the speakers, or any other output route) leaks back into the input (for example the microphone or any other input route). The effect is very distinctive as it causes a loud howl. Good luck w...

Even with modern processors, good, high quality convolution reverb is still pretty heavy (and Audacity does not yet support multiple processors), but yes, if you think that you can write a sufficiently efficient convolution reverb... ;) Probably the easiest way to get a working install of Freeverb o...

Many of the effects "below the line" in the Effect menu are "Nyquist Plug-ins". A limitation of Nyquist Plug-ins is that white space (empty selection) is treated as silence. "Nyquist" is a programming language that is separate from, but embedded in Audacity. When a Nyqu...

I would recommend using Audacity 1.3.13 http://audacityteam.org/download/

There is a Fade Out effect in the Effect menu.

When you connect a USB audio device to a Windows computer, Windows automatically allocates both input and output to the USB device.It may be necessary to go into the Windows Control Panel and in the "Sounds and Audio Devices" section, set the input and output devices to the devices that yo...

Using a tweaked version of the code in my last post: tracks000.png Track1 . Detected beats with the new code. Track 2. A click track at the same tempo as the music. Track 3. The music being analysed. Track 4. Output from beat.ny. The new code has picked out the beats pretty well, but has included a ...

I think that what is required is: a) Much more accurate beat detection (very tricky). This code pulls out beats pretty well in some music (mono track only): (defun filter (s-in) (highpass8 (lp s-in 2000) 40)) (defun track (s-in) (mult 100.0 (snd-avg (filter s-in) 100 100 op-average))) (force-srate ...

Accurate beat detection is very tricky. I could quite easily add a "beat count" to the Debug window of beat.ny, or adapt this BPM counter so that it outputs labels and shows the BPM in the Debug window. The main problem with both of these ideas is that beat detection for music is very poor...
