AB  - MPEG natural audio coders, as MPEG-1/2 Layer III and MPEG-2/4 AAC, require a great amount of calculation, mainly due to the iterative bit allocation processes proposed by the ISO/IEC technical documentation. This complexity makes difficult a real-time implementation of the normative algorithms. To solve this difficulty, this paper discusses a set of non optimal solutions to reduce the computing load and, based on these solutions, a real-time implementation of a MPEG-1/2 Layer III using a single fixed-point DSP is presented. In addition, techniques to achieve good audio performance and the methods for the adaptation of parameters will be discussed.
