I have a problem with a lot of my CD's. I'm sure this is familiar to a lot of people-the sound levels don't match. There's always that one CD that's a lot louder than the others, so you can't put it on mixes, etc. It looks like grip's "calculate gain adjustment" (encoding config, options tab) will be a step to fixing this problem for new tracks. Right? And then, what about existing .ogg and .mp3 files? Can I fix them, or should I just re-rip and re-encode? Thanks, Matt
