I have some time to burn and am bored. Alright, first let’s get it out there that I have never really considering doing this before and have no idea how to go about this. By converting my mp3s to OGG or FLAC, will the sound quality improve? Is it a simple & free process. I’d also consider using the Replay Gain feature as well.
MP3 is a lossy format, and no matter what you do, you cannot get the “dicarded” information back by re-encoding to another format. Now, if you are starting with a lossless original; like wav or flac, that’s a different story. There will be no audible gain from starting with a MP3 and changing to a different format.
