I tried all kind of SR combinations. Beside that I was told that top quality algorithms do not need synchronous SRC. Have a look at http://src.infinitewave.ca/ to figure out the artefacts associated to SRC. If you look at the graphs of top quality converters, you wouldn't expect any "data" related losses. You don't see any artefacts on 44.1 -> 96 conversions. I btw also tried Izotzope Adobe r8brain pro beside SOX, since some of tha AA fellows swear Izoptope or Adobe would be the leading packages. I could not tell a difference. That's why I stayed with Sox as a free package. Asynchronous vs. synchronous plays a bigger role in HW reclocking implemtentations. You might catch intermodulation problems. However. You can simply change the numbers and try by yourself. If anybody has a better idea. Shoot. I'm very open to try new settings. --- Regarding 24bit. It's not just the bitdepth. It's also the sample rate. A different sample rate requires reencoding to flacs. I btw have converted all my tracks to 24bit. Because I'm running server-based offline volume control using replaygain (EBU R128 compliant, applied with r128gain tool) tags + system specific attenuation offset. Doing it this way I can continue to stream PCM. Nowadays I run my main system without manual volume control. What a relief. --- ::: ' Touch Toolbox and more' (http://soundcheck-audio.blogspot.com) ::: by soundcheck ------------------------------------------------------------------------ soundcheck's Profile: http://forums.slimdevices.com/member.php?userid=34383 View this thread: http://forums.slimdevices.com/showthread.php?t=99088 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
