ACM stands for Audio Codec Manager. It's a DirectShow SDK's interface.
There's a lot of Software for Windows capable of using ACM codecs, like
Windows Media Player, VirtualDub, VideoMach and others.

No, its a user mode multimedia driver. Direct Show uses filters (COM objects).

Yes, but for Media Player you need a Direct Show filter for playback of FLAC
files. With an ACM driver this isn't possible. The best thing which you can
do
with the latter is to embed data into an AVI and even this doesn't work
well.
Once that you have multiplexed a non-fixed-sample-size audio stream into an AVI,
you can't edit it at sample granularity. (Naturally not. There are of course
several workarounds for MP3 e.g.)
