Re: Is there a way to get Dolby Headphone system-wide on any PC? Reply #25 – 2016-06-19 19:05:48 The dummy head BRIRS were recorded for 360° and have 720 channels. I reduced them to 16ch for 7.1 . The wav file have the channel configuration that is mentioned in the file name (L_R_C_LFE_LS_RS_LB_RB). For EQ-APO you have to make seperate wav files for every speaker. So you have to put the channels 1 and 2 into a seperate wav file (left speaker) , 2,3 into a seperate wav file (right speaker) 3,4 into a seperate wav file (center speaker).... The procedure would be the same for the DH files. For using more than stereo you need a sound device that allows you to choose 5.1 or 7.1 in the windows settings! Otherwise Windows will downmix to stereo before EQ-APO can do the convolution!
