- Recording and playing audio (on Unix-like systems)
- Editing via concatenate, trim, pad, repeat, reverse, volume, fade
- Processing via chorus, flanger, echo, phaser, compressor, filter (high-pass, low-pass, shelving, etc.)
- Speed (pitch and tempo), pitch (without tempo), and tempo (without pitch) adjustment
- Noise removal
- Simple audio synthesis

History
SoX was first released in 1992 by Lance Norskog. In 1995, Norskog released his final version of SoX; he has not maintained any version of SoX since that time. In 1996, Chris Bagwell released a modified version of SoX. On 2000-09-01, Bagwell registered his free "sox" project with Sourceforge. The announcement of the registration was made on the 4th of that month, and SoX 12.17 was released on September 7.
