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 ...

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 ...

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.

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 ...

On 29 June 2020, UNESCO Office in Beijing, together with NetEase Youdao Kada and Little Turing, announced the launch of the “2020 Beautiful Planet – Coding for Sustainable Development” initiative. It ...
