INF: Support for DSP Access in Microsoft Multimedia Windows ID Number: Q71149

1.00 WINDOWS

Summary:

Microsoft does not provide an application programming interface (API) to access digital signal processing (DSP) hardware in the current version of the Multimedia Extensions to Microsoft Windows. An API of this type should provide device independence, which is very difficult, given the diversity of DSP hardware configurations on the market today.

However, it is possible to access DSP functions through a higher-level API provided by the Multimedia Extensions. To provide this functionality through an audio driver customized to the particular DSP board, the Microsoft Multimedia Device Development Kit (MDDK) is required. The audio driver API is written to provide device independence.
