I know LMS is bit-perfect at 100% fixed volume, but I have the following questions: 1. there is also an adjustment for remote streams and the default value is -5. Is LMS still bit-perfect when I mess around with this setting? Should I keep it at 0? Or is it disabled at 100% volume? 2. How is it normal that roon and LMS are not equally loud at 100% volume? because remember roon is simply emulating LMS 3. when transcoding to flac from other formats, i see the following argument in convert.conf. [flac] -cs --totally-silent --compression-level-0 -. why is compression level a thing if the output is exactly the same? 4. can you or other knowledgeable members give roon a spin and comment on their implementation of LMS? sorry for the stream of consciousness questions but the issue fascinates me and i know the good people of the forum might shed some light on this ------------------------------------------------------------------------ mcduman's Profile: http://forums.slimdevices.com/member.php?userid=66702 View this thread: http://forums.slimdevices.com/showthread.php?t=114290 _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/ripping
