Rear outputs problem with ADI Surround

I'm working on a project with the AD194x. The goal is to use the ADI surround algorithm to upmix a stereo source. So far, my project looks like the exemple in the ADI Surround wiki page. Frequency sampling is 48KHz.


After multiple tests, I realize that the rear channels, LR and RS, sound unbalanced. To the ear, it sounds like there is more high frequency components in the RS channel. I tried the different modes, I swaped the outputs then the inputs, but the RS is always the louder channel.


Do you have any ideas what can cause this issue?
