Digital formats and data compression: Foundations of Digital Audio

Digital formats come in 3 main categories: uncompressed, lossless compressed, and lossy compressed. Matt explains how uncompressed files like WAV and AIFF and lossless compressed files like FLAC and ALAC contain the identical sample numbers & therefore sound identical. Lossy compressed formats using codecs (COmpressor/DECompressors) like MP3, WMA, AAC, and Ogg Vorbis trade off sound quality for much smaller file sizes. These codecs use a psychoacoustic model to minimize the audible quality loss.
