Nyquist
The scripting language many of Audacity's shipped plug-ins are written in.
Nyquist is a small audio programming language that Audacity can run directly. A Nyquist plug-in is a plain text file with a header describing the controls it wants, and Audacity builds the dialog from that header. Roughly half of what ships with Audacity 4 is written this way, including all four of the Tools and all three Analyzers.
Where to find them
Nyquist plug-ins appear in the ordinary Effect, Generate, Analyze and Tools menus alongside the built-in effects — there is no separate Nyquist menu. A Nyquist dialog is usually a plain stack of labelled fields, sliders and choices, without the knobs and graphs of the built-in effects.
Notes
Nyquist plug-ins process the selection as a whole rather than in a continuous stream, so they cannot run live during playback: none of them appear in a track’s realtime effects list.
Additional Nyquist plug-ins can be added with the Nyquist plugin installer, after which they are enabled from Plugin manager like any other plug-in.
