WAVEOUTEXTCAPS (Windows Embedded CE 6.0)

1/6/2010

This structure contains extended device caps information.

Syntax

typedef struct tag_WAVEOUTEXTCAPS {
  DWORD dwMaxHwStreams;
  DWORD dwFreeHwStreams;
  DWORD dwSwMixerSampleRate;
  DWORD dwSwMixerBufferSize;
  DWORD dwSwMixerBufferCount;
  DWORD dwMinSampleRate;
  DWORD dwMaxSampleRate;
} WAVEOUTEXTCAPS;

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.
