Questions tagged [sox]

SoX (Sound eXchange) is a computer program for audio manipulation. Questions about interactive use of the command line tool should be asked on Super User.

Sound eXchange, abbreviated SoX, is a free cross-platform digital audio editor, licensed under the GNU General Public License.

It can read and write many audio formats, including AU, WAV, AIFF, MP3 (via an external LAME MP3 encoder), Ogg Vorbis and FLAC. Some random features :

  • Editing via concatenate, trim, pad, repeat, reverse, volume, fade, splice, normalise
  • Recording and playing audio (on many systems); playing via URL (internet file or stream)
  • Processing via chorus, flanger, echo, phaser, compressor, delay, filter (high-pass, low-pass, shelving, etc.)
  • Adjustment of speed (pitch and tempo), pitch (without tempo), tempo (without pitch), and sample-rate
  • Noise removal using frequency profiling
  • Silent passage removal
  • Multi-file merging, multi-file and multi-track mixing.
