AKSOUNDENGINE_API AKRESULT AK::SpatialAudio::ReverbEstimation::EstimateHFDamping	(	AkAcousticTexture *	in_textures,
		float *	in_surfaceAreas,
		int	in_numTextures,
		AkReal32 &	out_hfDamping
	)

Estimate the high frequency damping from a collection of AkAcousticTextures and corresponding surface areas. The high frequency damping is a measure of how much high frequencies are dampened compared to low frequencies. > 0 indicates more high frequency damping than low frequency damping. < 0 indicates more low frequency damping than high frequency damping. 0 indicates uniform damping. The average absorption values are calculated using each of the textures in the collection, weighted by their corresponding surface area. The HFDamping is then calculated as the line-of-best-fit through the average absorption values.

引数

in_textures	A collection of AkAcousticTexture structs from which to calculate the average high frequency damping.
in_surfaceAreas	Surface area values for each of the textures in in_textures.
in_numTextures	The number of textures in in_textures (and the number of surface area values in in_surfaceAreas).
out_hfDamping	Returns the high frequency damping value. > 0 indicates more high frequency damping than low frequency damping. < 0 indicates more low frequency damping than high frequency damping. 0 indicates uniform damping.
