I am using HQPlayer as upsampler in my Roon setup on a Mac Mini 2012 and I am really enjoying the increase in sound quality.
My living room has two opposing hard walls that create some reverberation at about 3000 Hz, so I am using the convolution option in HQP to dial that frequency down a bit.
I made a single 192 kHz impulse wav with REW. Works very well!
In my tweaking efforts I sometimes make another impulse wav and load it in HQP. I point HQP at the same wav for left and right convolution. After that I find out that the left and right channels have been (randomly) changed. I found it out because I also use HQP to change the left-right balance a bit by reducing the left channel by 1.5 dB. That is then applied to the wrong channel.
I am using HQP 3.14.1
Any thoughts or similar experiences?
