Future Work MPEG-1 audio lays the foundation for all modern audio compression techniques Lots of progress since then (1994!) MPEG-2 (1996) extends MPEG audio compression to support 5.1 channel audio MPEG-4 (1998) attempts to code based on perceived audio objects in the stream Finally, MPEG-7 (2001) operates at an even higher level of abstraction, focusing …

The basic method by which audio compression in MPEG technology is done by MPEG encoder and decompression by MPEG decoder. Figure 3 shows block diagrams of the MPEG/audio encoder and decoder.[15] Thirdly, adjacent filter bands have a significant frequency overlap [15In MPEG compression the input audio stream passes

• MPEG/audio provides a means of including ancillary data within the bitstream. In addition, the MPEG/audio bitstream makes features such as random access, audio fast forwarding, and audio reverse possible. 2. OVERVIEW The key to MPEG/audio compression is quantization. Although quantization is lossy, this algorithm can give "transparent",
