A set of C# native implementations of various audio codecs:

• An MP3 encoder / decoder, based on LAME and Jump3r.
• A G.729 encoder / decoder based on libjitsi/Atlassian code.
• A G.711 encoder / decoder

Released under the LGPL v3.0.

Compiles to a .NET Standard 2.0 DLL and will run on .NET Framework >= 4.6 and .NET Core >= 2.0.

Fully managed code, no external OS dependencies, cross platform.

Not the most polished or optimised code; if you want efficiency you should be using LAME via NAudio or something like that.

Some of the Jump3r java code was converted to C# using the Free Edition of the Java to C# Converter produced by Tangible Software Solutions - https://www.tangiblesoftwaresolutions.com

NOTE: this is still alpha code, and the GroovyMp3.dll interface is likely to change
