DSP Plug-in User Overview
[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 It has been superseded by MediaPlayer.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.]
To the user, DSP plug-ins are add-on features that somehow change the way the user experiences the audio or video that Windows Media Player is playing. The result of a DSP plug-in could be something obvious, like the colors in the video image being reversed so it looks like a photographic negative, or something very subtle, like a light reverb effect in the audio to add a feeling of spaciousness to the sound.
Users can install and uninstall DSP plug-ins by using the Plug-ins tab of the Options dialog box in Windows Media Player. Users can then enable and disable installed plug-ins using the checkboxes provided on the Plug-ins tab. DSP plug-ins may implement a property page, which users can also access from the Plug-ins tab. A property page provides the user with a way to change settings that affect the way a DSP plug-in works. For example, a property page might include a slider control that allows the user to change the decay time of a reverb effect.
