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.

  • 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.
