I am sorry if this was discussed here, but I didn't found answer in search.
Please! Can anybody explain me why 3.90.2 lame.exe used with RazorLame and Drop Xpd bundel (using 3.90.3 LAME - downloaded from RareWares) give different files on standard preset (standard -Z on 3.90.2)?
Don't know about other presets, standard is realy different. 3.90.3 produces bigger files. And the difference isn't constant. The bigger wav (mp3) the bigger difference. There were no tags in compared mp3s! Please don't answer '...in these compiles were used different switches...'. It's a pure mathematics and if there are more bits they must do something. It drives me crazy

Why not just standardize on one of them...and leave it at that. There may subtle changes...hence the version bump from .2 to .3. 3.90.3 reportedly is the best (or at least the most tested) version to date. You ought not use when it is free software.

It has the same differences as john33's P4 optimization experiment: http://www.hydrogenaudio.org/forums/index....ST&f=15&t=8198&

Most of the time, the output is absolutely identical, but sometimes there's a difference. Listening to the difference signal, i somehow doubt that it's ABXable (though i haven't tried). It must be due to the compiler setup or the compile switches, resulting in rounding differences. The bigger file has potentially the better quality.

was adressed to myself. Since I can't understand so simple thing. I am very grateful to all people participated in LAME project and of course don't criticize them.

Of course there are subtle changes (otherwise the size would be the same), but why not to know what do that bytes do, especially when everybody says that 3.90.2 APS -Z=3.90.3 APS. I just want to know the difference.
