SoundTouch.Net (nuget): The SoundTouch library is originally written by Olli Parviainen in c++.  Although a .NET wrapper library is available, this library aims to be a complete rewrite in C# It is an open-source audio processing library that allows changing the sound tempo, pitch and playback rate parameters independently from each other: * Change tempo while maintaining the original pitch * Change pitch while maintaining the original tempo * Change playback rate that affects both tempo and pitch at the same time * Change any combination of tempo/pitch/rate
