Are there any simple tools to normalize an .ogg-library of 10'000+ songs so that the volume is the same throughout all songs? Terminal or GUI doesn't matter, it only need to be simple. One caveat though, I don't want soft interludes/intermissions and ballads blown out of proportion. Preferably the process should find the overall gain of the album (I have all my CD's ripped into separate folders) and normalize the level thereafter.
