BeHappy is an AviSynth-based audio transcoding tool written in C#.

Originally created by dimzon at doom9's forum and hosted at CodePlex (via Internet Archive).

BeHappy is designed mostly for movie audiotrack transcoding. It's a powerful BeLight/BeSweet replacement with XML based plugin system for source, dsp and encoder plugins.

A rich selection of plugins is already integrated aswell most of the required encoder executables (except non redistributable encoders like most of the AAC encoders).

As prerequisite a working AviSynth environment is required to use BeHappy. If you have no knowledge about AviSynth, simply use the installer.
