Members
- dwMaxHwStreams
Maximum number of hardware-mixed pulse code modulation (PCM) streams. For example, if your hardware supports the MP3 format and has a dedicated stream for MP3 audio, the dwMaxHwStreams value would be equal to the number of hardware-mixed streams minus the MP3 stream. - dwFreeHwStreams
Number of available hardware streams. - dwSwMixerSampleRate
Preferred sample rate for the software mixer. A sample rate of 0 indicates no preference. - dwSwMixerBufferSize
Preferred buffer size for the software mixer. A buffer size of 0 indicates no preference. - dwSwMixerBufferCount
Preferred number of buffers for the software mixer. A 0 indicates no preference. - dwMinSampleRate
Minimum sample rate for a hardware-mixed stream. - dwMaxSampleRate
Maximum sample rate for a hardware-mixed stream.
Requirements
