I am somewhat ignorant regarding lossless compression codecs, and I was wondering about some of ya'lls opinion on the sound quality of some of the codecs. I have tried FLAC and Wavpack, and I liked the quality of both of them, but I couldn't really tell the difference between the two.

Also, in ya'lls opinion, is it really worth using a lossless compression codec instead of using say Ogg Vorbis or MPC?

Thanks in advance.

jmvalin:

Ok that's correct, you can have a look at the future data, but whatever useful info you want to keep, you have to store in the output file (so the unpacker has access to it, too).

There are many possible strategies, from fully adaptive to package-transform approaches, but what you gain somewhere you lose elsewhere..

Most of the possible approaches (including some very simple ones) can give asymptotically optimal compression - but the faster algorithms are often hybrid constructions (ie: never fully adaptive, never fully table-driven) wink.gif
