Rubber Band Audio
Mac OS Music
Rubber Band Audio allows you to speed up or slow down music recordings and change their pitch. It features BPM detection and sync and tempo controls, gives a huge range of usable stretch and transpose factors, and provides high-quality results suitable for musical use.
With Rubber Band Audio, you can stretch and transpose your music or voice recording using the sophisticated Rubber Band timestretcher technology developed by Breakfast Quay. You can audition all your adjustments live, and export the results as new audio files.

This version supports selecting a range from a track, in order to audition, loop, or export a section of your music. It also adds keyboard shortcuts (the cursor keys) for speed and pitch, and complete hi-resolution rendering on Retina displays. File export is sometimes faster than before and some bugs have been fixed.
