I'm a long-time fan/promoter of MC, largely because the development team "gets it" - they are full of great ideas and they also listen to their users. But when it comes to ReplayGain, I've been very disappointed by MC's lack of support (both the player itself and the development team). Yes, MC has implemented ReplayGain in a way that works well inside the MC environment. But the way ReplayGain has been implemented is not compatible (as far as I know) with any other software/players out there. I know it's not compatible with my player of choice - Rockbox - which is a real shame because I feel Rockbox is the spiritual equivalent (sharp developers trying to make the best product possible) of MC.
I raised this point over two years ago (
http://yabb.jriver.com/interact/index.php?topic=38695.0), and got some support from other frustrated users, but nothing happened. In the third post of that thread, Alex B describes what needs to be done to become compatible with Rockbox, Foobar, and Winamp (and if you're compatible with those three you're probably compatible with most players that support ReplayGain).
Now it may be that the way JRiver implemented ReplayGain is far superior to the way everyone else is doing it. That's fine. I'm not saying that that should be abandoned. But as a Rockbox user, ReplayGain is essentially unsupported. So
please add an option to analyze and tag files that is compatible with the rest of the ReplayGain world. I don't understand why this hasn't happened yet!
Cheers,
Fred
