Cool. Works well.

Keep on keepin on, with the updates that is. :)

The app does exactly what it says it will. Works well. I don't have a use for it as is, but it's still fun to play around with.

This would highly improve the app, and make it extremely useful: copy paste, audiobus, Audioshare compatible, ability to slice/edit the wave form.

Anyway a lot of that would probably be out of the scope of the original intent of the app.

Good stuff. Looking forward to updates.

Simple and powerful

As the name implies it has the capability to stretch your music files, great for transcribing music.
