SoX (Sound eXchange) is the venerable command-line utility for audio processing. It can convert between audio formats, apply effects, combine files, and generate test tones — all from a single binary with no external dependencies required for most operations.
While AI agents have limited direct integration with SoX compared to more modern tools, it remains valuable for straightforward audio tasks: trimming silence, converting formats, normalizing volume, and applying fade effects. Its simple syntax makes it easy to compose audio processing commands in automated pipelines.
SoX supports a wide range of audio formats including WAV, MP3, FLAC, OGG, and AIFF. Its effects chain allows stacking multiple operations in a single command — trimming, fading, resampling, and applying filters in one pass without intermediate files.
