There's a post higher up the thread on the -b option, but I'm supprised you need to use it at those parameters as the defaults are close to: -b 2048:3446. I'd expect you wanting to try making them bigger not smaller. (I'd leave the output one and adjust the input one) (I say close to as the option is multipled by 1024 to get the actual size and then rounded to a multiple of samples) There is nothing in the code to lock memory into ram at present (which squeezeplay has). I wonder if people are going to experiment with then whether we need to consider this. Will look into this - perhaps people can confirm which systems they are testing on for this, so that if I produce a test binary I can target it to the right one(s). Can't comment on DSD I'm afraid. ------------------------------------------------------------------------ Triode's Profile: http://forums.slimdevices.com/member.php?userid=17 View this thread: http://forums.slimdevices.com/showthread.php?t=97046 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
