Available on Hackage Build Status

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.
