Description

SoX is described as the Swiss army knife of audio utilities. It can read/write and migrate between many common audio formats. Note that MP3 is not directly supported due to patent concerns, but it can be added via LAME integration. SoX can also play, record and edit audio or be used as a digital audio processor, e.g. noise removal, applying impulse response filters.
