The Layer II coder provides a higher compression rate by making some relatively minor modifications to the Layer I coding scheme. These modifications include how the samples are grouped together, the ...

STMicroelectronics has announced an MPEG layer 3 audio decoder chip that also includes an embedded ADPCM (adaptive differential pulse code modulation) codec to allow voice recording and playback.

PARIS - Dec. 2, 2004 - Thomson (Euronext Paris:18453) (NYSE:TMS) today announced that mp3, the world's most popular audio compression format, goes multi-channel. Fraunhofer Institute for Integrated ...

We have Mp3 CD players now so (besides the obvious licencing issues) how would such a thing be pushed onto a chip. <P>Actually I'm more interested in how hard coding works than in this particular ...

Lossy compression schemes can be based on a source model, as in the case of speech compression, or a user or sink model, as is somewhat the case in image compression. In this chapter we look at audio ...
