Pwl works at a sample-rate "control-srate" thich is normally a 20th of the actual sample rate. This produces a fade-in over 20 samples and does also shorten the sound in some cases (where the remaining samples falls under 10 samples or so) You can use (control-srate-abs *sound-srate* <Pwl ...

... The window size is 16784 samples with 50 % overlap. Here's the code: (defun cosine (freq) (abs-env (hzosc (snd-pwl 0 *sr* (list 0 freq (1- *fr*)freq *fr*)) *table* -90))) (setf snd (send class :new '(sound))) (send snd :answer :isnew '(snd) '((setq sound snd))) (send snd :answer :next '() '( (l...

(snd-sqrt (snd-avg (mult s s) sr sr op-average))

Ahh, yes, I see, I've used only the copied form. Negative values produce of course nan-values.

The rms values are pretty much always reported as -1000. Taking the average sounds about right. the -1000 value indicates silence, normally, there would be written -#ind due to the log of zero. But I guess that you want the values to be in another scale For instance integer values 0 to 255 = Rms -1...

Manchester USA?
It is now 06:00 AM UTC and probably 10:00 PM in LA.
I have 07:00 AM MEZ.

Thank you to both of you. I tried running the version for pasting into excel (Which is fine by me), but the rms didn't seem to work properly. I'm guessing the simple (rms) version is fine. What does not work? Is it that the rms values are in dB, with -1000 as limit, rounded to 2 places? Everything ...

Because 'abs' works with numbers solely. Use 's-abs' instead.
However, this is not equivalent to your replacement code, which is a raised cosine.

You might want to look at this recent post: http://forum.audacityteam.org/viewtopic.php?f=20&t=78484#p241775 It should return those sounds you are looking for, always depending on the threshold. It has a constant time resolution though. It is clear that it would otherwise indrease the calculatio...

import the tracks (or a portion of them) Select all tracks, Track Menu --> Align Tracks --> End to End. You can now render those tracks into one or just go directly to Export. The key stroke to get to the end of the selected track(s) is K, if you need that in future; J does the contrary and goes to ...

The general rule is: The narration is always mono, regardless of direct or indirect speech. Dramatized scenes can be stereo. Pseudo stereo is pretty annoying when listening to it over some hours. The same is true for dialogs where each speaker is panned individually. Don't worry to much about female...
