APE, FLAC and WV are fast, what i can't say about LA or OFR.
LA and OFRbestnew is eating my P4 1.4 in playback mode (frog mouse) [foobar2000, xp]

Update: [JEN, superdumprob]

You forgot WavPack (wa). Its also very good!

That was quick!

Jaro: I thought bestnew was the highest compression setting in optimfrog... Maybe I'm wrong.

EDIT: Nope. I'm not wrong. But Ghido recommends extranew as the best compression for general use. I don't know if you were aiming for best compression or best general use compression but seeing that you went for the highest compression setting with all the other encoders I think you should use bestnew.

OK, updated.

I aiming for best compression, for best general use i think is multichannel, multiplatform and streamable format. (FLAC and what else?)

Indeed! I know bestnew is slow, it just seemed like you were going for highest compression. FLAC is pretty good for the purpose you say and there isn't all that much difference in the compression ratios of the lossless codecs. I saw someone's post who'd done a run through of the lossless codecs on 23GBs worth of wavs. I'll see if I can dig out a link later.

I saw it too .

Maybe here...?

That's the one banana. Thanks. Oh, and I like the signature. Heh heh.

Have fun peoples.

hmm. a bit outdated. there have been newer releases of optimfrog and la.

a bad thing that there is no valid performance/size comparison (as there are different modes for most encoders). Performance at a given size would be more interesting.

go to http://web.inter.nl.net/users/hvdh/lossles...ss/lossless.htm (there are many test cd. About optimfrog's compression ratio/performance: the last optimfrog 4.505 is the same than optimfrog 4.504).
