Getting convolution working

[Colin]

Hey,

I have a convolution crossfeed I use in linux with JamesDSP, which I'm
trying to get working in Windows 11 with EqualizerAPO.

This is the .wav I'm using -
https://github.com/Audio4Linux/JDSP4Linux/blob/master/resources/assets/irs/CorredHRTF_Crossfeed.wav

I thought I had it working. I'm definitely getting a crossfeed effect but
it's just not sounding as it does with JamesDSP. These are the commands I'm
using:

Copy: L_TO_L=L L_TO_R=L R_TO_L=R R_TO_R=R
Channel: L_TO_L L_TO_R R_TO_L R_TO_R
Convolution: CorredHRTF_Crossfeed.wav
Copy: L=L_TO_L+R_TO_L R=L_TO_R+R_TO_R

Sample rate is set in windows to 48000 hz to match the wav. Perhaps my
channel order is wrong, or maybe this wav just isn't compatible with how
the EqualizerAPO convolver works?

Any advice would be appreciated.

Reading the wiki it seems a bit difficult to deal with the channels. But Equalizer APO does this internally so your Copy: commands are unnecessary and also resulting in mixing the left and right channels which need to remain separate. Hence the sound not matching the sound in JamesDSP.

One way to go is by creating a stereo file (instead of the 4 channels one you now have) and just convolve it.
