Versions for OS 9, OS X, Windows, Linux, etc.Įisenkraut - A simlple free audio editor that, despite its BETA status, works quite well for basic tasks, and fills a hole of free basic audio editors for OS X. I use this for many of my basic audio editing needs. Includes hints at MIDI support in the future. Very promising offering unlimited audio tracks, VST effect support, ability to record while playing back (like a sequencer), mp3 and ogg export, non-destructive volume automation, non-destructive time warping tracks, spectral and pitch displays, I/O meters, and compatibility with many audio formats.
