Karlheinz Brandenburg · The Journal of the Acoustical Society of America · 2000
Perceptual coding of high-quality audio has found widespread applications for broadcasting, internet delivery of music and storage of music as used in portable music players. The success of formats like MPEG-1 Layer-3 (AKA MP3) can be attributed to the standardization philosophy of MPEG: A universal format is specified and available for licensing for everybody. This leaves the encoder up to technical improvements. The presentation will (i) introduce the basics of high-quality audio coding, (ii) give an overview on MP3 and MPEG-2/4 AAC, (iii) explain encoding strategies, and (iv) give special consideration to parameters affecting coding quality.
