Best Audio Conversion? MP3

[Hell Bomb]

Ok, not sure if this is the right section but this is the forum with some of the smartest people i have met when it comes to converting well anything. Anyways i got an entire library of music, mostly mp3, but i wanna convert them all to a single format, something with good quality and will keep all the song info that is already in the songs, but i wanna hopefully reduce the size. Do any of you guys know of a program that will convert my library, keep song info, and perhaps auto recognize best settings for music file(recognize best bitrate to encode at to keep nearly-exact quality)

You shouldn't convert one lossy format to another lossy format. Leave them alone. You can't make them sound any better.

However, AAC is probably your best bet if you're insistent on making them smaller.

Your task, as you explain it, is both pointless and impossible.

Size isn't a huge issue, just looking to convert them to a more stable format and perhaps optimize the files. I would like to maintain the quality.

i think the basic problem can be solved with the right features in your audio player.

i'm using foobar2000, which is by no means perfect, but has a few very useful features:

- mass tagger, and pretty advanced tag manipulation stuff (like extract tags from filenames, move files around and rename based on tags, lookup freedb and match your tracks to an album for fixing badly tagged tracks)

- replaygain (and R-128 gain via a plugin). this measures the loudness of each song, tags them with that measure, and then allows the player to play every song (or album) back at the same volume. this means you wont have to reach for the volume control between songs.

- converting to other formats. this way, you keep everything as it is, so you don't bugger the quality by transcoding. if you find you need to shift something from aac to mp3 for a particular device, you just transcode it then-and-there, and it'll place the encodes straight on that device. so your library stays clean, and your device can play the song.

- nice database stuff. you can search easily by genre, name, pretty much anything. you can sort by bitrate to help determine if you have doubled-up some stuff, and if so what to keep.

mp3repacker will convert ABR/CBR mp3 to VBR with lower bitrate.
It is lossless operation.

or If you have original CDs then encode them to AAC or MP3 with high quality encoder.

I think the OP should refer to the forum rules (http://forum.doom9.org/forum-rules.htm). Particularly rule 12
