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 doesnt 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...
