SoX was created in July 1991 by Lance Norskog and posted to the Usenet group alt.sources as Aural eXchange: Sound sample translator. With the second release (in November the same year) it was renamed Sound Exchange. 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). In May 1996, Chris Bagwell started to maintain and release updated versions of SoX, starting with version sox-11gamma-cb. In September 2000, Bagwell registered the project at SourceForge with project name "sox". The registration was announced on 4 September 2000[citation needed] and SoX 12.17 was released on 7 September 2000.
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.[2]
