Notes and Comments
- This format is also often referenced as "EA ASF file format" or "Electronic Arts SCxl"
- This format lists all files one after the other. Each file is split up into chunks, presumably to make for more efficient file buffering when playing audio.
- This file format supports several chunk types: SCHl (header chunk), PATl, TMxl, mTCD, SCCl, SCDl (data chunk?), GSTR, PT and SCEl (end chunk).
