[slim] Re: Where/how is gain adjustment carried out?
From these responses, I gather that the gain adjustment is performed at the player, but that it is done in the digital domain. This implies that it must be a 'lossy' process and should be turned off for best quality reproduction. This is a shame, because it does seem to me that, for the analogue outputs, it ought to be possible to adjust the analogue gain in response to the replaygain value and maintain a lossless reproduction. I guess that I'll leave Volume Adjustment turned off on my main system, but leave it turned on on the other SB which is used for casual/background listening. -- peterbell peterbell's Profile: http://forums.slimdevices.com/member.php?userid=7314 View this thread: http://forums.slimdevices.com/showthread.php?t=28462 ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

So for HDCD titles it's best not to scan the albums, and just leave it as it is? I use digital out to a HDCD capable DAC. -- badbob badbob's Profile: http://forums.slimdevices.com/member.php?userid=7358 View this thread: http://forums.slimdevices.com/showthread.php?t=28462 ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

But your decoder should indicate it's decoding HDCD as soon as ReplayGain is disabled. Note it'll have to be over digital, and the digital volume must also be at 100%. -- Mark Lanctot Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=28462 ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

Josh Oh yes, of course there is loss of information (and addition of false information) in the anologue domain but I would guess, unless there are some very serious non-linearities, the effect is seldom as obvious as the infidelities which could be introduced in the digital domain. However, it may be worth, as you suggest, setting up an ABX test so that I can judge for myself. I guess that, from a purist point of view, having elected to use FLAC coding for all my music, it goes against the grain to, knowingly, introduce unneccessary digital processing. -- peterbell peterbell's Profile: http://forums.slimdevices.com/member.php?userid=7314 View this thread: http://forums.slimdevices.com/showthread.php?t=28462 ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

Why would anyone serious about music reproduction use replaygain for anything other than casual listening, anyway? So add the calculated values to your files and then decide whether or not you ever want to use it - it's just a few tags that don't affect the actual audio data. It's great for music playback for background music, parties and other non-critical listening situations where the benefits outweigh the potential minuses. -- JJZolx Jim JJZolx's Profile: http://forums.slimdevices.com/member.php?userid=10 View this thread: http://forums.slimdevices.com/showthread.php?t=28462 ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

I had more or less the same question: http://forums.slimdevices.com/showthread.php?t=19946 dean blackketter;78006 Wrote: The replay gain adjustment happens at decode time and is independent of the master volume control (and the analog preamp gain control). It's a simple gain multiplier, calculated from the replaygain value stored in the tags. This was in response to the details in firmware, so this means it's done at the player. Regarding it being a lossless process I would venture to say it isn't - if the track is HDCD-encoded, ReplayGain implemented in SlimServer will disrupt HDCD decoding, which means it isn't bit-perfect. -- Mark Lanctot Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=28462 ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

ReplayGain definitely does affect the volume even when it's set to fixed. No doubt about that when you switch it off for a recent master it loud track with a -10 dB RG. :-) -- Mark Lanctot Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=28462 ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss
