Captured digital audio is widely available from speech, music, and natural sounds, most of which can also be algorithmically synthesized. Digital audio can be manipulated in a variety of ways, including editing (trim, split, join, ...), enhancing (amplify, denoise, ...), analyzing (visualize, classify, ...), and creating effects (pitch shift, adding reverb, ...).
The Wolfram Language provides fully integrated support for audio, including fast in-memory data and large out-of-core files. The built-in audio supports a range of uses, from immediate playing and scrubbing to advanced programmatic processing and analysis.
