Rubber Band Audio allows you to change the tempo and pitch of music recordings independently of each other.

You can speed up or slow down music recordings without affecting their pitch, transpose or adjust pitch precisely without affecting tempo, or change any combination of those at the same time.

Rubber Band Audio features BPM detection and tempo controls, supports a huge range of usable stretch and transpose factors through our own Rubber Band timestretcher technology, and provides high-quality results suitable for musical use.

You can open numerous audio formats (MP3, M4A/AAC, WAV, Opus and others), audition all your adjustments live, and export the results as new audio files in lossless (WAV) or lossy (M4A) formats.

You can even make adjustments to a whole folder of files at once, for example to adapt a whole folder of recordings to the same tempo.

Rubber Band Audio has a choice of colour themes integrated with the macOS dark mode setting, and is built for optimal performance on Macs with Apple Silicon as well as Intel.

Very Useful

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...
