It accepts any MP3 or audio file just like any other app. Open in, from email, dropbox. If you press the I (info button) it takes you to the help page and the first entry is how to get files into the application.
Return pitch adjustment
Response from developer
I agree. The library that I used to pitch shift just canceled support. They were going to disable the app, so I dropped support. I have implemented pitch shift again, but there's no way to contact you.
