ACM compressed sound description
The acm file extension seems to have been primarily related to an audio format featured in several computer games, including Fallout, Baldur's Gate or American Civil War.
Probably related to now obsolete Audio Compression Manager (ACM), which was a Windows multimedia framework for management of audio codecs (compressor/de-compressors). It was replaced by DirectX and its DirectShow component.
It seems there were several versions of this format and not all programs that support ACM may support all of the formats. Especially dedicated converters for game music usually just work for a specific game.
