The Smallest Audio File & Coverting

[Teac23]

Hi.

I have 2.38GB of MP3 files. I would like to put on a 700mb disc.

If this is possible. What would be the smallest audio format size could i convert to?

Thanks

File size = bitrate * running time

So use lower bitrates. WMA and AAC sound a little better than MP3 at low bitrates. But unless all your files are very high bitrates to start with reencoding to low enough bitrates to put them all on a 700 CD will sound pretty bad. For example, reducing 320 kbps MP3 to ~80 kbps WMA might sound ok, but reducing 128 kbps MP3 to ~32 kbps WMA will sound like crap (you might find it acceptable for simple voice recordings).

Are you using this for playback on a device or PC? or just archiving?

Beware many devices won't play back AAC or WMA and some won't even play MP3 on a CD

If for storage, why not use a DVD ?

As jagabo suggested, I wouldn't bother, because you are roughly reducing the bitrate/3 . So unless you are starting with 320kbps mp3, it's going to sound horrible.

They will sound like complete garbage if you re-encode them from their already lossy status.

Reencode them at about 1/3 of the current bitrate. Do one and see if the quality is acceptable.
(You can do this en masse using CDex, for one.)
