AudioLobe for Mac

AudioLobe allows you to alter the speed of audio playback without changing the pitch rate. If you are a musician or interested in audio this means you can slow down complex sequences of audio without the vocal or instruments sounding unintelligible.

Great for learning difficult notes in a musical sequence. For example, you can set a very small section of the audio to loop at whatever playback speed you want and easily follow what is happening, without having pitch changes.
