But, as far as I know, hardly any software uses the replaygain values stored in the LAME tag, so you might want to use --noreplaygain and use software like foobar2000 to compute the replaygain values instead, which stores the values in tags. Disabling the LAME replaygain calculation will probably give a small speed increase during encoding, but I haven't tested that. I usually use --replaygain-accurate just for completeness sake.
Do you know which software actually does support the LAME Replaygain header? How how it is supposed to handle Replaygain info if there is one in the header aswell as in the tags? Does the tag-info get priority over the header? I'm just wondering because foobar's Replaygain should give more accurate result (like --replaygain-accurate) as is computes the mp3 data. Things would go nasty when applying mp3gain to the files: say a track is gained by 6db. If the player now would take the unchanged value from the header (which still is at apr. at +6db), it would be gained twice and thus become much too loud!
