This directory contains a .NET interface for Rubber Band Library,
generously contributed by Jonathan Gilbert under a BSD-like
licence. The directory `rubberband-sharp` contains a managed-code
interface to Rubber Band in C#. It loads and uses the DLL defined in
`rubberband-dll`, that wraps the Rubber Band Library with an API
understood by the `rubberband-sharp` code.
If you make use of this interface, please ensure you comply with the
terms of its licence, in addition to the GPL licence accompanying
Rubber Band Library itself:
