The title says it all. I have tons of FLACs and every one of them has a copy in MP3 encoded in LAME 3.98.4 and some are in 3.99.3. 3.99.5 is the new latest version now, should this mean I have to re-encode those FLACs to 3.99.5? I would gladly want to hear opinions of others.

Joining in the choir here ...

You haven't even specified what settings you used. There were changes from 3.98.4 to 3.99 intended to improve upon quality. But that is quality for a given bitrate. (Also, some changes were done to the presets, I think, effectively changing the bitrate on a few of those.) So in principle, you could get fewer and less annoying artifacts for given bitrate. Or -- probably a more fruitful point of view -- the same subjective quality at a slightly smaller file.

If there are audible artifacts, then you should change the setting. By all means upgrade the version, but that's probably a smaller difference. (And if you do, check that the presets do mean the same, I think that the 'tuning on VBR scale and resulting bitrates' change to 3.99 means they don't.)

From 3.99.3? Only if you experience the issues addressed in the upgrade: http://lame.cvs.sourceforge.net/viewvc/lam...ml/history.html

IIRC, the changes in bit rate resulted in bigger files with the newest version; at least at -V0.

FWIW, I'm still encoding with 3.98.4. It works great for my purposes @-V3 so I haven't bothered to upgrade.
