KaraokeAudioPresentationMode Property

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The KaraokeAudioPresentationMode property sets or retrieves the right-left speaker mix for the auxiliary karaoke channels.

[iMode ] = MSWebDVD.KaraokeAudioPresentationMode

Return Value

Returns an integer value containing a set of bit flags indicating how the auxiliary karaoke channels are downmixed to the left and right speakers.

Remarks

This property is read/write with a default value of zero.

Audio channels are zero-based, so channels 0 and 1 generally represent the right and left speaker channels and channels 2 through 4 are the three auxiliary karaoke channels. When the MSWebDVD object enters karaoke mode, it automatically mutes channels 2 and higher. Use bitwise OR operations to set the appropriate bit in order to send an auxiliary channel to the left speaker, right speaker, both speakers (both bits on), or to no speakers (both bits off). These bits are all off by default whenever the DVD Navigator enters karaoke mode. The value of the bits and their corresponding action is given in the following table.
