Nyquist plug-ins are plain text files which can be read with any simple text editor. For example you can load the .lsp files from the Audacity "Nyquist" folder or the .ny files from the Audacity "Plug-Ins" folder into your favourite text editor and try to find out how they work. That's how many people learned Nyquist programming. Many additional Nyquist plug-ins can be found here.

Basic Experiments
Experiments from the Audacity Nyquist prompt:
- Changing the volume of an Audacity audio track
- Changing the volume of the left and right stereo channels independently
- Changing the volume with envelopes - fade in, fade out, etc.
- Changing the volume with a low frequency generator - tremolo effect
- Increasing/decreasing treble and bass - simple equalizer
- Timeshift with Nyquist - simple delay effect - Audio loops with Nyquist - simple loop and echo effects...
Advanced topics
- Narrowing and widening stereo signals
- Removing vocals from a stereo recording
- Writing your own Audacity Nyquist plug-ins
- Official Audacity Nyquist plug-in documentation
- Updated plug-in information, 2007
- Nyquist 2.36 manual - the current Nyquist 3.0 manual is not compatible with Nyquist in Audacity
- XLISP documents collection - XLISP is the programming language Nyquist is based on
We are currently working on unifying the old Nyquist plug-in documentation on the main Audacity website and the updated information in the German forum into one single place here in the Wiki (then removing the current Nyquist downloads page on the main site ). The only disadvantage of this is that the potential (unused) mechanism for translating this page is lost. Doing this was never a priority as the plug-ins themselves are in English. Possibly we could in time add (at least, German) translations of Wiki Nyquist pages, or even links to German versions of these plug-ins?
Very advanced topics
- Multiple echoes with different delay times - reverb effect
- The relations between timeshift and frequency response
- Frequency-dependent delays with comb and allpass filters - reverb, chorus, phaser, etc.
- Dynamics processing - how to derive control signals from volume behaviour
- Auto-equalizing - how to derive control signals from frequency behaviour
