I need to pitch shift audio files in an Android app.
The files can be in any format, as far as I'm aware.
I know for sure I can't use javax.sound. I need to try to stay away from licensed products to get this done, but I've been searching for a way to do this since Monday, so I'm open to all suggestions.
Thank you in advance.
use the following library: https://www.surina.net/soundtouch/ I'm using it myself presently. Checkout README to compile and there's also an example for android which works just fine . feel free to ask any query.
Edit:Also Checkout superpowered SDK
