What it does
SoX, Sound eXchange, converts audio files and applies sound-processing effects during conversion. Its official project page identifies GPL and LGPL licensing.
Use a combined conversion-and-processing workflow when an audio file needs both a new format and an effect. This keeps related transformations in one tool rather than passing several intermediate files between applications. The exact format handlers depend on the installed build, so consult its documentation when a workflow relies on a less common audio source.
Strengths
- Combines audio format changes with signal-processing effects.
Best for
- Audio processing tasks that accompany format conversion
