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 ...

Partners’ proof-of-concept for next-generation video coding technology positively evaluated by the ITU-T Video Coding Experts ...

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 ...

MP3, the format that revolutionized the way we consume (and steal) music since the 90s, has been officially retired -- in a manner of speaking. The German research institution that created the format, ...

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 ...
