AudioSpeed is an audio playback processing application that allows you to hear your audio file at different speeds without altering the pitch, or with the pitch altered without changing the speed. Or a combination of both. Great for learning difficult notes in a musical sequence. You can set an adjustable section of the audio to loop at whatever playback speed you want and easily follow what is happening, without having pitch changes. AudioSpeed also works with video files. AudioSpeed is available now at the Mac App Store for Mac OS X 10.6 and 10.7.
