I just used sox to convert "Here Comes The Sun" from 24-bit to 16-bit
and re-calculated replaygain (using metaflac).
Convert command:
sox 24-bit.flac --bits 16 16-bit.flac
Results:
Original 16-bit file (ripped from CD):
comment[10]: REPLAYGAIN_TRACK_GAIN=-3.93 dB
comment[11]: REPLAYGAIN_TRACK_PEAK=0.95849609
24-bit file from USB stick:
comment[13]: REPLAYGAIN_TRACK_GAIN=-4.14 dB
comment[14]: REPLAYGAIN_TRACK_PEAK=0.98062515
16-bit file converted from 24-bit file:
comment[13]: REPLAYGAIN_TRACK_GAIN=-5.34 dB
comment[14]: REPLAYGAIN_TRACK_PEAK=0.98117065
So, either my convert command is wrong, or it's reasonable to expect a
converted 16-bit file to have a different peak level than the 24-bit source.
