Audacity Forum

I apologize to all as rewriting someone's code is usually considered rude. Don't worry about that, I also learned Nyquist by re-writing plugins of others. Problem: Audacity_1.3.13 refuses to load your plugin because there are lots of unreadable characters, so I can't test your plugin. If I look at ...

For a mp3 recorder you can use Steve's Soft-Clipping Limiter or the RFT-Limiter-IV.

We need more information about the "peaks": Is this a pure speech signal? Are there background noises or are the peaks from the voice only? Maybe you could provide a short uncompressed audio example? (no MP3 please) Instead of removing the peaks in a postprocessing step it would be much easier to us...

Two problems: 1. In the video there are four audio tracks but Audacity internally is limited to "one track at a time". This means that you can't write a plugin like "do this with the first track, do another thing with the second track" and so on. If several tracks are marked with the mouse then Auda...

Yes, "nyquist.lsp" says: (defmacro control-srate-abs (r s) `(progv '(*CONTROL-SRATE*) (list ,r) ,s)) And (1.0/len)*(1+len) is the longwinded version of (1+len)/len, so here now simplified and with "control-srate-abs": (defun fade (sound fade-out &optional fade-in) (let* ((seconds (/ len *sound-srate...

Lisp (Nyquist) symbols have hypens in their names and are really awkward to read if automatically broken into pieces at the end of a line, so the question is: How do I protect words-with-hypens against automatic line breaks? In HTML this usually works with <nobr>...</nobr> (deprecated but works), bu...

To avoid nasty click-sounds at the beginning or end, a Nyquist envelope is defined as always to start and end with a zero-sample. Because your envelope ends with 1.0, Nyquist adds a fade to zero at the end. The solution is described in the Nyquist manual under Piece-wise Linear Functions : If you re...

The details how Nyquist internally works and the history how and why Nyquist was created can be found under Functional Languages for Real-Time Control . The particular problem with arrays is that a simple array is not enough. With a simple array the processed sound cannot be bigger than the computer...

Hi jotti, Nyquist controls sounds via functions and return values, not with arrays like C or C++, so with Nyquist you must think like an audio engineer, not like a C programmer. Below is some code containing a "pan" function (simulating the "pan" knob of the Audacity audio track), and some code wher...

steve: Search this page for "snap to:" ...

Thanks (and sorry), the "Features List" is where I should have looked first.
