XAudio2CutoffFrequencyToRadians function
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.

-
The cutoff frequency in hertz. Frequencies greater than SampleRate ÷ 6 are clamped to XAUDIO2_MAX_FILTER_FREQUENCY.
- SampleRate [in]
-
The sample rate of the audio data affected by the XAUDIO2_FILTER_PARAMETERS structure.
Return value
Returns a radian frequency for use in the XAUDIO2_FILTER_PARAMETERS structure.
