IXAudio2SourceVoice::GetFrequencyRatio method

Returns the frequency adjustment ratio of the voice.

Syntax


void GetFrequencyRatio(
  [out] float *pRatio
);

Parameters

pRatio [out]

Returns the current frequency adjustment ratio if successful.

Return value

This method does not return a value.

Remarks

GetFrequencyRatio always returns the voice's actual current frequency ratio. However, this may not match the ratio set by the most recent IXAudio2SourceVoice::SetFrequencyRatio call: the actual ratio is only changed the next time the audio engine runs after the IXAudio2SourceVoice::SetFrequencyRatio call (or after the corresponding IXAudio2::CommitChanges call, if IXAudio2SourceVoice::SetFrequencyRatio was called with a deferred operation ID).

For information on frequency ratios, see IXAudio2SourceVoice::SetFrequencyRatio.
