Digital data compression techniques can be applied to a whole range of different signals, including speech, audio, images, video, radar, and computer data. The basic algorithms used are often quite similar [ 1 ], with particular structures, combinations of techniques, and optimizations for different types of signal.

Sound Compression ! Some techniques for sound compression: ! PCM - send every sample ! DPCM - send differences between samples ! ADPCM - send differences, but adapt how we code them ! LPC - linear model of speech formation ! CELP - use LPC as base, but also use some bits to code corrections for the things LPC gets wrong. !

FLAC (Free Lossless Audio Codec) is one of the few audio formats that delivers truly lossless compression. FLAC is similar to a ZIP file, but is designed specifically for audio. FLAC is also open-source, and FLAC files can be played back on most MP3-compatible players.

Digital audio compression allows the efficient stor-age and transmission of audio data. The various au-dio compression techniques offer different levels of complexity, compressed audio quality, and amount of data compression. This paper is a survey of techniques used to com-press digital audio signals. Its intent is to provide
Lossless Compression ofAudio Data

Various data compressor techniques which have developed in past are compared. A comprehensive list of references is reported and the data compression techniques are classified in to following main types: 1) lossless compression; 2) lossy compression. The objective of this paper is to identify various compression techniques that can be useful in the

Deflate Compression It is totally dependent on above two techniques It gives three different modes to compress data: 1)Not compressed at all 2)Compression, first with LZ77 and then with Huffman coding(The trees that are used to compress in this mode are defined by the Deflate specification itself, and so no extra space needs to be taken to store those trees.) …

The proposed method uses two lossless compression methods namely simple compression by eliminating LSB and compression/decompression algorithm with a CR constraint. The processing time of this method is low and makes it more suitable for implementing in real time applications.
