Filtering or improving the audio quality of mp3s? Options

[PokeYouInDaEye]

Are there any software programs that will improve the listening experience of an mp3, perhaps using some "intelligent" technology to fill-in the compressed information in an mp3?

Futher, what program do you recommend for re-mastering mp3s (volume, EQ, etc.)?

For volume, there is ReplayGain, which only tells the player to adjust volume, without reencoding. Must be supported by the player though, and I don't know if any DJware does.


The 'lost data is lost' argument is really invalid, if the encoding used an inferior psychoacoustic model (for example, if used one quick and dirty mode, or a fifteen year old encoder) -- then in principle, it might be possible for a better model to detect more-probably-than-not-an-artifact parts of the signal. For example, a pop/crackle remover for digitized vinyl tracks does that: it guesses on your behalf.

Anyway, I asked the same question a few weeks ago. No luck.

Then use Mp3gain. Any player will support that.
