Abstract :
MPEG-4 audio coding is a recent audio standard that integrates a wide range of different types of audio coding, and, thus, applies to almost every audio application today. A very important subpart of MPEG-4 is the Advanced Audio Coding (AAC) algorithm, which has already distinguished itself in industry due to its high audio quality. This paper describes implementation of an AAC decoder on a novel dual-DSP architecture utilizing cost-effective 24-bit fixed-point arithmetic.
