Roon ROCK Core with NUC7i7BNH cannot play DSD files with Convolution filter (Acourate) [Answered]

Hi @brian

I found this old thread and this user seems to have to similar issue

A little convolution problem with DSF tracks [Resolved - bad file header]

Yes sure there is a problem somewhere. In fact I have the same problem using Ron bridge on my minimal fedora install or when I’m using squeezelite on another fedora minimal installation or with other distribution such as Ubuntu. So it doesn’t seem to be relative to the endpoint which is used, apparently. I’m using wav filters made with Acourate, 64bits 131072 taps for the sample length in wav format, I’'m using a zip folder with these impulse wav stereo files with sample rates from 44100 to 3…

I am not sure the cause either, but when I do A/B test with or without “Native DSD Process” on, with Native DSD Process on+Convolution, the vocal is definitely shifted to the left.
Native DSD Process off (DSD converted to PCM first), no crosstalk with Convolution filter

Let me clarify:
DSD–>Convolution–>DSD Crosstalk
DSD–>PCM–>Convolution Normal

I have 8 filters from 44.1 to 384k, no DSD filter in the zip.
Do I need CFG files in the zip so that Roon will recognize which WAV to use for Convolution each bitrate?

I can provide you with zipped filters as needed if you want to investigate the phenomenon.

Right now, it is not too much of a problem for me, and I don’t mean to cause any trouble as you informed me you guys are working on at the different Convolution Filter already
I will use the Path above for now as it is more stable also (9.4x), and sounds good too.
