An easy way would be to take the code from SilenceFinder.ny oder SoundFinder.ny an apply in the silent parts more background noise then in the sound parts.

controls:
noise mix (sound)
noise mix (silent)
level for silence

1. I found an effect in AddNoise: The resulting volume is a mixture from the original sound and the background sound. That means if you start with the parameter set to 20 the resulting original sound is only about 80% of the original volume. Is that indented? Is there a workaround? 2. Is there an ea...

My multichannel version is getting errors, whatever I try: (setf s1 s) (setf s2 s) (seq (multichan-expand #'extract-abs 9 10 (cue s1)) (multichan-expand #'extract-abs 0 1 (cue s2)) ; (multichan-expand #'s-rest 0) (s-rest 0) ) And why Nyqust doesn't take "The logical stop time" of the last element fo...

I've changed your last code to Can you explain me, why the s2 part of the result is 9 seconds in the result?

I took a sound of 2 min and made a fade in over 2 min for a better visual recognition. Then i applied some code to test the seq command. (Please comment in or out the different seq lines) (setf s090 (multichan-expand #'extract-abs 0 90 s)) (setf s90pl (multichan-expand #'extract-abs 90 (get-duration...

Many thanks for the code.
A first try of a plugin is attached.

AutoDuck would be great, but can I use it form within a Nyquist plugin?

I know how I can to that (see subject) manually. Unfortunately I have to process a lot of mp3 files. Am I right, that Audacitys batch mode won't help me without a plug in? How can I add for example a brown noise to a track by using Nyquist? Can I use within Nyqusit another track with music to add th...

Here is a stereo expansion of SilenceLength.ny My anyone have a look or try it , whether there are any bugs? Is that the hack that I wrote? I notice that it always inserts silence at the beginning, so that is probably a bug. Yes, It's from your post here at Jan 12, 2010. Does it really make silence...

Is there any further developed version of silencelength.ny?

Is there another similar plug-in?

Truncate Silence would do it, but unfortunately it end at 1:1, so I can't do an decompression.

Any other tips?
