Nyquist is an elegant and powerful language for sound synthesis and music composition. Unlike score languages that tend to deal only with events, or signal processing languages that tend to deal only with signals and synthesis, it handles both in a single integrated system. It is also flexible and easy to use because it is based on an interactive Lisp interpreter.

Nyquist is a language for sound synthesis and music composition. It is implemented in C and C++ and runs on Win32, OSX, and Linux. Nyquist combines a powerful functional programming style with efficient signal-processing primitives.

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.

A sampling theorem for discrete signal processing where the original image can be reconstructed without distortion if it is sampled at a spatial frequency (2f) at least twice that of the maximum base frequency (f).

The minimum sampling frequency required to sample analog signal is at least twice the maximum of the highest frequency of the analog signal. This criteria for the sampling is called Nyquist Criteria.
