摘要：
Efficient implementation of MPEG-2 Advanced Audio Coding (AAC) decoder on low cost 16-bit fixed-point DSP needs some techniques to reduce the computational complexity. In this paper, we introduce an extra gain factor to adjust the value range of the spectrum data, and by adapting other techniques such as FFT, a low cost and high quality WEG-2 AAC decoder is obtained.
