Sorry, it was a pacat problem, not sox's: the proper syntax for the pacat command is: $ pacat --record -d alsa_input.usb-BEHRINGER_UMC404HD_192k-00.analog-surround-40 --channels=4 --channel-map=aux0,aux1,aux2,aux3 > dump2.raw and then sox: $ sox -t raw -r 44100 -e signed-integer -L -b 16 -c 4 dump2.raw output2.wav This way it seems to work. Do you tink it's correct? Thanks, Rodolfo _______________________________________________ Sox-users mailing list Sox-users@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/sox-users
