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.
See our website for more information!
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.
Ratings and Reviews
I play in a band in which our singer often needs to change the key for optimal vocal quality. I just downloaded it, and it does what it’s supposed to do. Very simple and easy to use interface. I can now practice along with the original recording in the proper key. Assuming it continues to work, it’s totally a five star app!
Does exactly what it is supposed to!
I was having the hardest time transposing audio files down a whole step to practice guitar parts in the right key. It used to take me about 15 mins per song to transpose the audio in ProTools. With this app it has now decreased down to about 30 seconds a song. Rubber Band doesn't do a lot, but it definitely does what it is supposed to do, and it does it well. Also works with .mp4 files which is huge. I highly recommend this app...
I’m a professional mix engineer, and occasionally need to change tempos of a cut song or loop, but I really need those changes to be totally transparent. This is the best app I’ve ever heard for this purpose (and I include my high end mix tools in that comparison.) Amazing value, with the highest quality.
With Family Sharing set up, up to six family members can use this app.
