Note: Now, for the holy grail of lossless audio codecs, FLAC.

FLAC was originally made in 2001 by Josh Coalson, but was later adopted by the Xiph.Org foundation, who you will hear about several times throughout this presentation.

It started as a fully open standard with no royalties, and is the most popular lossless codec for music.

Many things are able to play it, even some lower end music players have FLAC support.

Similar capabilities to ALAC as well.

Made by Xiph Foundation
