Abstract
When MPEG AAC encoders are implemented on 16-bit fixed-point processors, the constraints of low complexity and limited data word length become challenges especially on the critical algorithm, Psychoacoustic Model (PAM). This paper proposes a very efficient PAM design concerning the reduction of memory requirement and computational complexity while maintaining the audio quality. © 2005 IEEE.
