MPEG Audio Compression Basics This is one of many methods to compress audio in digital form trying to consume as little space as possible but keep audio quality as good as possible. MPEG compression showed up as one of the best achievements in this area. This is a lossy compression, which means, you will certainly loose some audio

Abstract. MPEG Audio was the first international standard for high quality audio coding and it opened the doors to a variety of applications in the world of digital music. In this chapter we review the basic ideas and features behind the general purpose, perceptual audio coders specified in the MPEG-1 and MPEG-2 audio standards which include the MP3 and AAC …

• 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",

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 Compression Algorithm Basic Algorithm. The above figure shows the basic MPEG audio compression algorithm. It proceeds by dividing the input into 32 frequency subbands, via a filter bank. This is a linear operation that takes as its input a set of 32 PCM samples, sampled in time, and produces as its output 32 frequency coefficients.

MPEG-1 Layer 3 (or MP3) is a 1- or 2-channel perceptual audio coder that provides excellent compression of music signals. Compared to Layer 1 and Layer 2 it provides a higher compression efficiency. It can typically compress high quality audio CD data by a factor of 12 while maintaining a high audio quality.

MPEG uses a matrix called quantizer (Q [i,j]) to define quantization step. Every time when a pixels matrix (X [i,j]) with the same size to Q [i,j] comes ,use Q [i,j] to divide x (i,j) to get quantized value matrix Xq [i,j]. Quantization Equation Xq [i,j] = Round (X [i,j)/Q [i,j])
