CreateAudioMediaType function (audiomediatype.h)

The CreateAudioMediaType function uses the format specified by the caller to create a media type object that describes the audio format.

Syntax

HRESULT CreateAudioMediaType(
  const WAVEFORMATEX *pAudioFormat,
  UINT32             cbAudioFormatSize,
  IAudioMediaType    **ppIAudioMediaType
);

Parameters

pAudioFormat

Specifies a pointer to a WAVEFORMATEX structure.

cbAudioFormatSize

Specifies the size of the WAVEFORMATEX structure pointed to by the pAudioFormat parameter.

ppIAudioMediaType

Specifies a pointer to an IAudioMediaType interface.

Return value

The CreateAudioMediaType function returns S_OK if the call to the function is successful. Otherwise, it returns an appropriate HRESULT error code.

Remarks

When you implement custom audio system effects, the CreateAudioMediaType function works with IAudioSystemEffectsCustomFormats::GetFormat to represent a custom audio data format and to provide information about the custom format.
