16 bit audio indeed has a theoretical noisefloor at -96dB relative to full scale (dBFS). This has nothing to do with loudness. ReplayGain assumes people have volume calibrated audio systems, where a pink noise signal with -20dBFS will result in an absolut loudness of 83dB SPL (sound pressure level). Or pink noise at -14dBFS resulting in 89dB SPL. 83dB SPL has been found to be the average absolute loudness the large majority of audio engineers felt is just right for movie soundtracks and classical music. 89dB SPL is for pop music. http://www.digido.com/bob-katz/level-practices-part-1.html ReplayGain scales the tracks up or down so that their weighted average corresponds to the target of -14dBFS (which on a calibrated system translates to 89dB SPL). But since people don't have calibrated systems, ReplayGain will only serve the purpose of equalizing relative volume between tracks/albums. Target volume shouldn't be set too high, or chances are that RG will scale volume up even on tracks which are already clipped/distorted due to excessive volume (almost all mainstream albums nowadays). -- Raptus ------------------------------------------------------------------------ Raptus's Profile: http://forums.slimdevices.com/member.php?userid=1852 View this thread: http://forums.slimdevices.com/showthread.php?t=44938 _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/ripping
