- Extreme pitch and tempo changes (for instance 24 semi-tones, which is quite a lot!) can lead to noise.
- Voice reduction quality depends on the input. It works best with little compressed music and assumes that voice was recorded in mono and later mixed into the stereo channels (which is the case for a lot of music recordings)

Ratings and Reviews
Great app but I'm upset about something...
There's no email option, and I have wasted around a whole week trying to figure out how to enable file sharing, and where to find it. I still haven't figured it out and I'm very angry and upset and I think there should be an update containing the option to Email creations. Please, do this ASAP. Don't change anything else because then you might make the app too complicated and I've been looking for a simple app like this for a very long time.
Please read my review and consider making it easier for some of us to save our creations, not everyone is computer-smart, you know. :)
Best sound quality for slow down
I was just using this app and it was good for slowing down the tracks to hear better what is going. But slowing down a track digitally usually makes it sounds so badly that you can barely stand it. But then I discovered a setting for HQ or high quality. When you turn it on, it clears up most of the digital artifacts present when you slow music down. Even at 50% speed the music still sounds decent. Way to go app developers! No other product that I have used can do this. Also, the ability to take either track to mono can help isolate the instrument you are trying to transcribe. And finally, the button to remove vocal can also work to cancel the bass, since it is also mixed to the middle. This is great for bass players as a play-a-long where you become the bass player on the recording. Both these features need a stereo track to be effective.
Works amazing (but requires money)
RECOMMENDED FOR PEOPLE WHO JUST WANT TO CHANGE THE PITCH OR TEMPO OF A SONG!!
The quality of the songs are great, nothing is lost in the saving or transfer process and sounds exactly like you just bought it.👌
For me, all I want to do is edit some of the songs I have to a higher or lower tempo/ pitch because it’s more pleasing to me. However in order to get to that I had to play 2.99 for the advanced options. But hey if the qualities great and I don’t need to pat 20 bucks or more for some fancy computer software that has hundreds of extra tools I don’t need, it’s completely worth it.
