Returns the channel mask for this voice.
- pChannelMask [out]
Returns the channel mask for this voice. This corresponds to the dwChannelMask member of the WAVEFORMATEXTENSIBLE structure.
This method does not return a value.
The pChannelMask argument is a bit-mask of the various channels in the speaker geometry reported by the audio system. This information is needed for the X3DAudioInitialize SpeakerChannelMask parameter.
The X3DAUDIO.H header declares a number of SPEAKER_ positional defines to decode these channels masks.
SPEAKER_STEREO // SPEAKER_FRONT_LEFT (0x1) | SPEAKER_FRONT_RIGHT (0x2) SPEAKER_5POINT1 // SPEAKER_FRONT_LEFT (0x1) | SPEAKER_FRONT_RIGHT (0x2) // | SPEAKER_FRONT_CENTER (0x4) // | SPEAKER_LOW_FREQUENCY (0x8) // | SPEAKER_BACK_LEFT (0x10) | SPEAKER_BACK_RIGHT (0x20)
Note For the DirectX SDK versions of XAUDIO, the channel mask for the output device was obtained via the IXAudio2::GetDeviceDetails method, which doesn't exist in Windows 8 and later.
Windows 8, Windows Phone 8 (XAudio 2.8)
