About the Sample Audio DSP Plug-in
[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The sample audio DSP plug-in provides a simple processing implementation that scales the amplitude of the audio by a factor provided by the user in the property page. The plug-in accepts values between zero and 1. The default value is 1. A value of 1 has no effect upon the sound; other scale factors are multipliers for the audio samples. For instance, a value of .5 would result in a 6 decibel decrease in volume. A value of zero results in silence.
The sample audio DSP plug-in works with stereo or mono PCM audio.
