Try as I might, I couldn't find a way to quickly, reliably reverse a sound in Nyquist. Arrays are really slow, shape is slow and cranky, and worst of all, snd-reverse does not exist.

I had need of this recently, so posting the snippet here. Say you have two variables "var1" and "var2", and you want to swap their values so that "var1" takes the value of "var2" and vice verse. This requires creating a temporary variable. For example: (setf t...

The Nyquist function S-REVERSE is not defined in Audacity's version of Nyquist, so if it is necessary to reverse a sound in a Nyquist plug-in, then a suitable function must be written. For short sounds, this can be done quite simply, by reading the the sound into an array, reversing the array, and t...

Documentation page for that is currently not working. The page addresses are case sensitive: https://manual.audacityteam.org/man/scripting.html Would it be possible to activate a python script during recording with one key press? Probably easiest to do that with something like AutoHotKey , as that ...

Can anyone provide some more "for dummies" type explanations of the various settings on these plug-ins and how to use them?

The only "documentation" for this effect is here: viewtopic.php?p=245549#p245549

On Ubuntu 18.04, I've compiled the current alpha version (2.3.1, evening of 1/10/19) with mod-script-pipe enabled. Congratulations. :) Export2: Filename=test.m4a NumChannels=2 That "should" fail. The filename needs to include the full path, so something like: Export2: Filename=/home/smart...

Several of the libraries have been updated over the past 6 years. You may be able to get suitable versions from 2.0.0 / 2.0.6.

I can't stand the jumpiness of the playhead and the lagginess of the output level monitor in later versions

Which of the more recent versions have you tried?

If you use a 64-bit Mac, you may want to try out 2.3.1 when it comes out (later this month) as it will be a 64-bit app.

I'm curious why you want to base your efforts on an obsolete version of Audacity.
