XAudio2CutoffFrequencyToRadians function (xaudio2.h)
Inline function that converts from filter cutoff frequencies expressed in hertz to the radian frequency values used in the Frequency member of the XAUDIO2_FILTER_PARAMETERS structure.
float XAudio2CutoffFrequencyToRadians(
[in] float CutoffFrequency,
[in] UINT32 SampleRate
);
[in] CutoffFrequency
The cutoff frequency in hertz. Frequencies greater than SampleRate ÷ 6 are clamped to XAUDIO2_MAX_FILTER_FREQUENCY.
[in] SampleRate
The sample rate of the audio data affected by the XAUDIO2_FILTER_PARAMETERS structure.
Returns a radian frequency for use in the XAUDIO2_FILTER_PARAMETERS structure.
You must explicitly define XAUDIO2_HELPER_FUNCTIONS in your build for this function to become available.
