Peter 27Dec16: Landing page under construction for Nyquist pages in process of being transferred from the Audacity Website.

The page title is a "working title", I'm open to suggestions for a revised title.

  • Peter 28Dec16: No longer a working title and not really mutable as I have this afternoon fixed up a large number of links in the manual to come to this page with this name.
Nyquist is a programming language for sound synthesis and analysis based on the Lisp programming language. It is an extension of the XLISP dialect of Lisp, and is named after Harry Nyquist. It can be used to write plug-in effects for Audacity.

The Nyquist programming language and interpreter were written by Roger Dannenberg at Carnegie Mellon University, with support from Yamaha Corporation and IBM.

Nyquist Programming

Nyquist was written by Roger B. Dannenberg and was intended to be used as a complete programming language for audio synthesis and analysis, with support for MIDI, audio recording and playback, file I/O, object-oriented programming, profiling, debugging and more.

Audacity uses only a subset of Nyquist’s functionality, allowing you to take simple Nyquist functions and use them to process audio data. Audacity doesn’t include any support for debugging Nyquist code, so if you are trying to write a complicated plug-in, you may find it easier to get the full version of Nyquist and develop there, then turn it into an Audacity plug-in. Nyquist is available from the Carnegie Mellon University Computer Music Project. You can ownload the full Nyquist from here: CMU Computer Music Project Software.

Getting Started

The following are a set of three linked tutorials to help get you started with progamming in Nyquist for Audacity.

Nyquists Programming Reference

Peter 27Dec16: Is the above (pre-existing) Wiki page redundant now that we have the three pages transferred from the Wiki? Should it be incorporated in Programming in Nyquist? Or if neither - would it benefit from a retitle, or a retitle of Programming in Nyquist?

Nyquist Documentation

This page is intended primarily for people that wish to write Nyquist plug-ins or gain an insight into how Nyquist is used in Audacity.

For users that only want to download Nyquist plug-ins please see below.

Nyquist Plug-ins Reference

This page offers a detailed look at the structure and syntax of Nyquist Plug-ins. It is intended for people who wish to write their own plug-ins.
