I am working on a research project and struggling on finding information on some of the more technical details about the working how MP3 and FLAC works to encode and compress its data.
Most information I find (via Google) is a bit too high level where it basically a says that MP3 uses lossy compression and FLAC uses a lossless compression, but doesn't go much into detail.
I am specifically trying to find what algorithm it uses to encode and decode its data to and from audio, and how MP3 determines what information to be loss.
Any help on where I can find some more information on this topic. is appreciated.
