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 ...

One company that has managed to remain relatively obscure despite making gargantuan contributions to the pro audio field is Fraunhofer IIS. Headquartered in Germany, the Fraunhofer Society is one of ...

The ATSC has published two new Candidate Standards documenting enhancements to the AC-3 digital audio compression standard and specifying its use in digital television. This is a major step toward ...

An ordinance from the Ministry of Internal Affairs and Communications (MIC) was issued in 2011 on revision of the audio coding formats of 8K Super Hi-Vision (8K) broadcasting using 22.2 multichannel ...

We are currently researching a video and audio coding technologies for advanced terrestrial broadcasting. Here, we present a real-time versatile video coding (VVC *) decoder that supports multilayer ...

Audio codecs are one of the fundamental building blocks of modern media systems. The first and still most prominent MPEG audio codec is mp3, which first appeared on the market in 1998. Since then, ...

In MPEG Layer III coding the compression gain is mainly achieved through the unequal distribution of energy in the different frequency bands, the use of the psychoacoustic model, and Huffman coding.
