Great tool

I am 62 years old. I have guitar and bass played professionally my whole life. There are pieces of music I have tried in vain to learn for years that I have been able to pick out in minutes with this app. Nice tool

Great app! Speed up or slow down music!

This is fantastic for music teachers who need to speed up or slow down a piece of music. When working with students who need a section slower for learning purposes you can slow it down to help work notes that are unmanageable to learn up tempo. Or to speed up a section of a recorded accompaniment to help with breath control (start fast and slow down as breath control improves). Great music teaching tool helper!!
Only issue: Professional recorded sound is great - changes don't alter pitch - but non-professional recorded things, the speeding up or slowing down creates some audio artifacts - but still 99% pitch unchanged. Amazing!!

I just downloaded this app to try and did not like the ads so I paid for the purchase. Everytime I try to replay my recording, the app instantly crashes and closes. I have notified their Support. If they are unable to fix, I will ask for a refund.
