Audio Representation

The Wolfram Language provides fully integrated audio support, including fast and efficient in-memory data, as well as large out-of-core local and remote files. The built-in audio enables a range of uses, from immediate playing and scrubbing to advanced programmatic processing and analysis.

Creating & Importing Audio

Audio create an audio signal from an array of data

AudioCapture capture an audio signal from an input device

AudioGenerator generate noise, oscillator, and more
