I'm about to launch into a debugging session to see why mp3gain (http://mp3gain.sourceforge.net/ ) and madplay 0.15.1b don't seem to be playing together (no pun intended). I thought I'd ask if anyone has used the two together yet, or if there is another linux-based replaygain processor (for adding replaygain to existing mp3s) that is more reliable.
map3gain does appear to be adding a tag, as it finds it again if rerun over the same file.
From my brief look at the mp3gain code I couldn't find evidence that it is actually writing a Replay Gain tag. It appears instead to be modifying the global_gain field of each Layer III frame. This modification should work with all players with or without Replay Gain support, though there may not be any indication of it.
Thanks Rob.
I see the trick. It's linked off replaygain.org, and uses the *algorithm*, but doesn't write the standard replaygain mp3 tags. It *does* write some custom tags in the APE standard though.
I'll see what improvements I can come up with.
