I was searching earlier an open source audio link earlier today where I downloaded a 53 min piece in flac-format.

I had not heard of it before and found this site:

http://flac.sourceforge.net/

They claim free lossless audio coding, and I noticed the 300+ Mb file became 500+ Mb wav-file after decoding.

My question: How can they claim lossless?

Are they saying those 200 Mb difference are wasted info anyhow?

i first heard of this on the metallica website. didn't really care much about it, but you've sparked my curiousity again. think i'll check it out.

Perhaps I could read deeper into it, but I guess perhaps someone here has a bit more indepth knowledge.

I think if this is as flawless as they claim I could free up quite some room on my HD seeing my last song taking up close to half a Gig allready.

yes its lossless - its a compression format

you would lose 200 MB using zip or rar too !

the difference is flac (and shorten and ape) can all be read compressed into winamp - so yep youll save yourself some space too !

it's 1:1 with the original. i just spent the weekend flaccing my old backup cds (audio&wav) to flac, saved a lot of space without losing quality. if it wasn't lossless, they shouldn't call it FLAC, anyway

http://flac.sourceforge.net/format.html might not clear things up too much but its worth a read if you're into tech specs n details...

There are a number of lossless compression tools available that achieve similar compression ratios with no loss in sound quality. Of those, Monkey's Audio and Shorten are probably the most popular. Generally lossless compression gives 2:1 compression at best, less for very noisy material, better for quieter stuff (classical, for instance).

Flac is excellent. Fast, free, well supported (except on Macs, but what is?), good developer community. Give it a try!
