Hi,
I wanted to share this here, in case it may be useful to someone from the AngelScript community: as part of a larger project, we have written a small set of utilities (in angelscript language) that let you read and write audio files in wav format:
Wave file reader/writer source on GitHub
It just requires arrays and the file add-on. It does not actually play the wave file but lets you load the audio data in memory and write them from memory.
