As far as I know, R128 as ReplayGain isn't really considered final yet (see http://wiki.hydrogenaud.io/index.php?title=ReplayGain_2.0_specification for example), so it would probably be a bit early to update this in the FLAC source. op 16-06-14 10:15, Olav Sunde schreef: > I mention metaflac because there are a few shell scripts that > use it to write RG tags in a flac music

I mention metaflac because there are a few shell scripts that use it to write RG tags in a flac music library on Linux. With support for Ebu R128 gain in metaflac (the calculation according to specification, not an external program) it would be easy to use, just change the cmd line for metaflac in the script. Now that metaflac supports sample rates higher than 48kHz this would be a good thing in

I haven't seen anyone make any concrete proposals for how it should change. Maybe I missed something. AFAIK, the only objection to it is that there is no way to distinguish between whether

Why metaflac only? flac is also able to calculate RG values. And, as far as I can see R128GAIN (http://r128gain.sourceforge.net/) is a standalone app, not a library. So probably it would be difficult to reuse its code in flac/metaflac.

Hi has anyone looked at adding R128gain code to metaflac so we can select to use this calculation for RP tags rather than replay gain?

Hi, I think I might have kind of, sort of found a bug in opusenc. But do correct me if I am worng. :) When converting an FLAC file that contains RG tags written by bs1770gain the resulting opus file has a way, way too high RG value. I am talking >90dB(!). Here is the metaflac output of the flac file: % metaflac --block-number=2 --list bs.1770/test.flac METADATA block #2 type: 4

I've recently encoded some older CDs to flac that ended up with a positive album ReplayGain value. (+2.0dB) Problem is they sound noticeably quieter then other albums when played through winamp. (Album mode and ReplayGain are on) When played through foobar2000 they are louder as I would expect. I did a few tests. When the Preamp is down to -24 all playback is very quiet. When I put it up

This question is mainly directed at John Edwards, I believe. I'm attempting to use oggdec.exe in a batch conversion of ogg vorbis files for use on a portable player. I'm using the -o option to redirect output to the LAME encoder. So far so good. However, I also want to do volume leveling using the replaygain tags. If I specify track (radio) gain, everything works fine, however, when I

FYI, Unless you've been checking the FLAC site you might have missed some encouraging things that have happened in the last few months. I haven't really been announcing things in the lists along the way, but to summarize: - Primus and Phish have been selling soundboard recordings of shows in FLAC - Magnatune (an indie label) offers their whole catalog in FLAC and Vorbis now - More
