Re: Audacity is limiting my volume?
I think SoundForge usually uses ASIO drivers. (Audacity can't be shipped with ASIO support due to licensing issues). Do you know if SoundForge is using ASIO in your set-up? That could account for the difference. I'd expect this problem to just be a matter of getting the settings right for the Window...

Re: Improvement to the vocoder effect
"That is crazy" : Yes, sure is. "Somebody should research why." : I've brought it to the attention of the powers that be. Actually, I've just noticed that it was not logged on bugzilla, so I've now added it. "xlisp is all written in platform neutral C" : Yes, sure is. ...

Re: Improvement to the vocoder effect
Or do you mean, Nyquist in Audacity runs slower on Windows than it does on Linux. other way round. Nyquist in Audacity runs slower on Linux than Nyquist in Audacity on Windows. I've not compared standalone Nyquist on different platforms, but for Nyquist in Audacity the difference is very large, som...

Re: Improvement to the vocoder effect
I don't get yet why the q factors are chosen as they are. If I recall correctly, the usual formula for converting between bandwidth and q for a bandpass filter is (Lisp notation): (/ (sqrt (power 2 N))(- (power 2 N) 1)) where "N" is the "octave bandwidth". For values of N less t...

Re: Change Speed - Stretch audio to a specified length
Steve, you could perhaps include high-quality resampling apart from the linear one. Thanks for the feedback Robert, "High Quality" resampling is included in the "change-speed.ny" effect (in first post of this topic). The "Lite" version, which I've called "StretchA...

Re: Improvement to the vocoder effect
I combined three setf-s into a single serial setf in the superstitious belief that it's marginally faster, which may be only negligibly true, and I don't mind to see that change reversed again by you. I think that is true (though quite a small difference). Also, PSETQ is fractionally quicker than m...

Re: Improvement to the vocoder effect
Here is another thing to fix that I didn't: if you apply the effect to a mono track, the effect fails with no informative message about how to use it properly. When Nyquist first appeared in Audacity, I don't think that it was anticipated that it would have a great deal of practical use, but was ra...

Re: Improvement to the vocoder effect
I actually read the sources for the interpreter I'm impressed. Definitely worth doing but not something I've got round to :oops: here is garbage to collect whenever a variable declaration is discarded, and that is what happens in each loop pass that has an inner let. That makes sense. I've not stud...

Re: Improvement to the vocoder effect
I believe that a let or let* INSIDE a loop is a thing to avoid with this lisp implementation, better to reassign something declared at loop top or outside. Is that correct? If the value of the binding is constant, then definitely yes. ;; slow version (dotimes (i 4000000) ; big enough to time (let (...

Re: Improvement to the vocoder effect
I suppose I don't need to explain that I applied the two effects to identical inputs, inverted one, and mixed, and verified with sound finder and looking at spectrogram, that the result is all silence. A good way to check that two tracks (32 bit float) are identical is to invert one, Mix and Render...
