Sound eXchange (SoX) is a cross-platform audio editing software.

[1] SoX was created in July 1991 by Lance Norskog and posted to the Usenet group alt.sources as Aural eXchange: Sound sample translator.

Norskog continued to maintain and release SoX via Usenet, File Transfer Protocol (FTP), and then the web until early 1995, at which time SoX was at version 11 (gamma).

Throughout its history SoX has had many contributing authors; Guido van Rossum, best known as creator of the programming language Python, was a significant contributor in SoX's early days.
