Audacity Forum

Ok, all is clear, 2 (stereo) tracks, 4 channels in total. I suggest that you first download my tool and place it in the Audacity plug-in folder. After that, you can restart Audacity, select both tracks and use "Remove Vocals". With a little bit of luck, one of the two versions will be yet ...

It is weird that you are left with the voice only. Normally, it is the other way around. If you're using my tool, you can try a +/- 45 degree rotation to put the voice in the center and to remove it then. Or you isolate the vocals/center which should be the music in your case, in dual mono though. T...

The vocoder is shipped with Audacity. It works pretty well, once you've got the hang of it.

Chris' Compressor allows expansion if the compression factor is negative. The parameters for a master limiter could probably be guessed. The attack/release is usually very short. The ratio goes towards infinity (Hard Limiter, not recoverable), at least 1:10 and the threshold is often a integer value...

I've used the above submitted code to "filter" out some prominent beats in the following example The original loop is at the beginning. This loop is then analysed at 12000 Hz (that's made with "reson"), this leaves kick and snare (the high pitch of beater and stick are found). Th...

How to extend the limitation?

You're doing something terribly wrong if you need such a resolution.

Is that what you want? ;; return first derivative (defun differentiator (s-in) (biquad s-in 1 -1 0 1 0 0)) ;; main function (defun get-times (snd-in threshold hold result) (let* ( (*sr* (snd-srate snd-in)) (hour (round (* 3600 *sr*))) (peaks (snd-oneshot (s-abs snd-in) threshold hold)) (start-stop (...

Have you seen my recent plug-in "Tempo Teller"? The current version is: rjh-tempo-teller.ny I've decided not to work with single sample values. If you wanna do that, you should resample the audio track. My algorithm is roughly as follows: - take 30 s, resample to 51200 (100* 2^9) - create ...

I would first try to compress the pauses.
This is less audible. It is available under 'Effects', 'Truncate Silence'. It needs a little bit experimenting to find the right compression ratio and perhaps the threshold. Use it only on spoken passages.

Could you tell us on which song you are trying to remove the vocals?
