Replay gain works by multiplying each sample with the gain value. I've seen the code. Also, you can't do any correction in "the additional bits" because these bits are in the -96db+ rande and I doubt you'd bother to do any replay gain that faint. And if you don't want to get into rounding errors and just bit-shift (which is _not_ what is happening) you'd have to change volume in -3dB steps but that won't give you "even" volume.
On some systems gain (both replay gain and volume control) can be used separate from the actual music info, under certain circumstances iPeng is doing that (depending on the output hardware) but it's not what the Squeezeboxes are doing and you can't do it with digital audio outputs (SPDIF et al), I'm not 100% sure about USB audio (AirPlay does it, the old iPod interface with the 30 Pin connector did it). This is usually done _instead_ of moving to 24 bits. --- learn more about iPeng, the iPhone and iPad remote for the Squeezebox and Logitech UE Smart Radio as well as iPeng Party, the free Party-App, at penguinlovesmusic.com *New: iPeng 8, the Universal App for iOS 7 and iOS 8* ------------------------------------------------------------------------ pippin's Profile: http://forums.slimdevices.com/member.php?userid=13777 View this thread: http://forums.slimdevices.com/showthread.php?t=87364 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
