The Audio compression basically utilizes MPEG 1 standard which is a generic audio compression standard. Audio compression in MPEG unlike vocal coders have coders known as encoders that do not assume the nature of source which generates audio signals but coder itself designs by hearing ability of the consumer at the output Multimedia II.

• 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",

In 2005 MPEG released two algorithms for lossless compression of audio, MPEG Audio LosslesS coding (ALS) and Scalable to LosslesS coding (SLS). Both provide perfect (i.e. lossless) reconstruction of a standard Compact Disc audio signal with a compression ratio approximately 2:1.

Two major competitive methods of audio compression are in widespread use in digital television systems: MPEG-1 Layer 2 and Dolby AC-3. Much of Europe and the U.S. DSS satellite system have chosen MPEG-1 Layer 2, whereas the U.S. cable industry and the U.S. broadcast standards use AC-3.

Comparison of MPEG audio compression standards 34 • MPEG 2 AAC - more efficient than the previous MPEG audio standards - supports from 1 to 48 channels at sampling rates of 8 to 96 kHz • MPEG 4 AAC - similar to the MPEG-2 AAC standard, with some minor changes - supports the compression of natural audio at bit rates ranging from 2 up to 64 kb/s.
Explain MPEG compression process in detail.

Explain MPEG compression process in detail. MPEG compression removes two types of redundancies: Pixel values are not independent, but are correlated with their neighbors both within the same frame and across frames. So, to some extent, the value of a pixel is predictable given the values of neighboring pixels. It is removed with the help of DCT ...

5.3.8.3 MP3 and AAC Compression [aside]MPEG is an acronym for Motion Picture Experts Group and refers to a family of compression methods for digital audio and video. MPEG standards were developed in phases and layers beginning in 1988, as outlined in Table 5.3. The phases are indicated by Arabic numerals and the layers by Roman numerals.[/aside]
