Abstract: MPEG-4 AAC is the widely used audio standard and getting more popular for commercial use. MPEG-4 AAC (Advanced Audio Coding) incorporates several innovative technologies in order to achieve high Fidelity at low bitrates. MPEG-4 AAC is the widely used audio standard and getting more popular for commercial use. This paper presents an investigation & implementation of low complexity profile high quality MPEG4 AAC Audio Decoder at a sampling frequency of 44 KHZ on a Field programmable gate array. Through this paper we discuss IMDCT filter bank, Noiseless decoder, Inverse quantiser and Scale factor application modules of MPEG-4 Advanced Audio Coding decoder more efficiently

Keywords: high quality, low complexity
