Oh yes, but don't forget, ReplayGain suggests a gain *that would work out to 83 dB*. From 'here' (http://replaygain.hydrogenaudio.org/outline.html): > The reference gain is 83dB SPL, as defined in the SMPTE RP 200 standard. Knowing this, if you want 89 dB, just add 6 dB to the suggested gain to get 89 dB. All fine and good for foobar2000, which just adds 6 dB if the slider is set at 0 to get 89 dB, but SlimServer uses only the suggested gain, which will play back at ~83 dB. What DrNic and myself would find useful would be to have ReplayGain's standard at something other than 83 dB, which is far too low compared with almost any other audio source you'd have connected to a preamp: CD, Internet Radio through the SB (which is MUCH, MUCH louder!), DVD, etc. If you just invoke the FLAC encoder with the "--replay-gain" switch, you'll get suggested gains to bring the playback volume to 83 dB. Again, MP3Gain does this using the ReplayGain algorithm for MP3s. It's very evident when you play around with the MP3Gain GUI what's going on. Once the files are scanned, when you alter the "Target "Normal" Volume" field, the suggested gains immediately change in all files. ReplayGain analyzes the files and suggests an initial gain, MP3Gain just alters the suggested gain and doesn't alter the analysis. It would be tricky to modify ReplayGain, so it would be better to modify the suggested gain RG writes into the tags. I suppose this could be done in a hex editor, but it's a little klunky to do this for every file! foobar2000 also provides a means of editing the RG data, but it's manual and it's one-at-a-time. Now I'm not sure, but this might screw up foobar2000. It would see the suggested gains and think "oh this is at 83 dB, I need to add 6 dB to it", but if it's at 89 dB already, it would bump it up to 95 dB. I don't know if there's any other RG data that says "this track is at 85.4 dB, track gain is therefore -2.4 dB to get to 83 dB". If there was, it might be possible to edit the RG data to keep the calculated volume of the track and instead say "this track is at 85.4 dB, track gain is +3.6 dB to get to 89 dB". But I use SlimServer/Squeezebox for serious listening, not foobar2000, so it doesn't bother me if foobar2000 plays too loud or clips. -- Mark Lanctot ------------------------------------------------------------------------ Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=20746 _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/ripping
