Audio Driver Development Concepts (Windows Embedded CE 6.0)

1/6/2010

The Audio Device Manager is just a common name for the OS code between applications using the waveform audio API and audio device drivers. It manages audio devices, includes the software-based mixer in the kernel, and handles various aspects of security, interprocess communication, application callbacks.

**The audio driver architecture for Windows Embedded CE supports driver creation using the unified audio model (UAM) as well as the MDD and PDD model. The architecture also supports various types of audio compression manager (ACM) drivers such as codecs, converters, and filters.

The following illustration shows the Windows Embedded CE audio stack.
