Ok got it ! I did what you said, adding my sound card to the jconvolver config /# Replace by whatever required... # /cd /root/folve/filter # # in out partition maxsize # --------------------------------------------------------------- /convolver/new 2 2 1024 65536 # # # num port name connect to # ----------------------------------------------- /input/name 1 in.L hw:sndrpihifiberry /input/name 2 in.R hw:sndrpihifiberry # /output/name 1 out.L /output/name 2 out.R # # # in out gain delay offset length chan file # -------------------------------------------------------------------------- /impulse/read 1 1 0.75 0 0 0 1 T-Monacor_SPH30X.wav /impulse/read 2 2 0.75 0 0 0 1 T-Monacor_SPH30X.wav # / and the procedure is now : 1/ start jack2 : jackd -d alsa -r 44100 -p 256 -n 16 -P -S exact ? 2/ start jconvolver : jconvolver filter-44100.conf 3/ Start squeezelite : squeezelite-arm -o jack I get sound, and it is convoluted However, now I would like to know if all this could be done without jack ? I have the feeling the sound is not as good as what I got from BruteFIR or from Folve I don't want to use none of these as they both have their drawbacks. Any idea os suggestion to make my setup better ?
