Modeling of an MPEG Layer-3 Encoder and Decoder in Ptolemy Literature Survey

MPEG Audio Layer-3, or “MP3,” has rapidly become the most popular format for the encoding and compression of digital audio and has found widespread application in both hardware and software. This literature survey provides a brief introduction to the MPEG (Moving Picture Experts Group) standard for audio encoding and explores the feasibility of formally modeling an encoder and a decoder. It also describes some of the available literature on the MPEG standard and associated research. The tremendous popularity of the standard has led to a large amount of literature, research, and source code related to the encoding and decoding of MPEG audio. The focus of the actual project will be a model of an MP3 encoder and decoder in Ptolemy [1]. This model will be used to generate C code that can be compared, in terms of speed and memory efficiency, to several of the widely used codecs currently available.
