Binding to the C++ audio stretching library Rubber Band.
Rubber Band Library is a high quality software library for audio time-stretching and pitch-shifting. It permits you to change the tempo and pitch of an audio stream or recording dynamically and independently of one another.
Rubber Band Library is open source software under the GNU General Public License. If you want to distribute it in a proprietary commercial application, you need to buy a license.
This is a binding to Rubber Band Library v1.8.1.
This is a Haskell binding to the Rubber Band audio stretching library. Two interfaces are provided:
The low-level interface,
Sound.RubberBand.Raw, gives you simple access to the C API.The higher-level interface,
Sound.RubberBand.Nice, offers a garbage-collected state object and easier memory management via Haskell vectors instead of pointers.
A sample application wavstretch is also provided to demonstrate the high-level interface.
Now available on Hackage, so you can install with cabal install rubberband.
