High performance software implementation of MPEG audic encoder
Abstract
The MPEG/Audio is a standard for both transmitting and recording compressed audio. The MPEG algorithm achieves compression by exploiting the perceptual limitation of the human ear. The standard defines the decoding process and also the syntax of the coded bitstream. However, there is room for having different implementations to generate the compressed bitstream. In this paper we propose a high performance software implementation of the MPEG/Audio encoder. We obtained more than a factor of five improvement over a straightforward implementation on the IBM PowerPC, Model 250.
