Detailed Description

HRTF: holds the data that corresponds to an HRTF for a single position. It has a list of complex buffers for the FFTs of the HRIR, typically 16 blocks of 512 each for an 8k HRTF. This version knows how to parse the IRCAM hrtfs sets Subclasses could load different HRTF sets (e.g., CIPIC).

HRTF::HRTF

(

)

generic constructor allocates all data

HRTF constructor allocates memory for the HRTF data and then reads the HRIR file and performs the block-wise FFT

HRTF::HRTF	(	char *	fname,
		FFTWrapper &	fft
	)

load an HRIR file and do FFTs
