Audio Compression Manager Drivers (Windows CE 5.0)
ACM drivers are stream interface drivers.
Like other stream interface drivers, the Device Manager controls ACM drivers, and they expose standard stream I/O functions. However, unlike other stream interface drivers, applications do not use these drivers directly.
ACM drivers are called by the ACM, which sends messages to ACM drivers when applications need to play or record sounds.
