This paper is about the methods of sound data compression. The development of audio data compression has significantly made our lives easier. The technological progress has facilitated the process of recording audio on different media such as CD-Audio. In recent years, much has been achieved in the field of audio and speech compression. Many standards have been established In order to compare methods of sound data compression I have used Adobe Audition 3.0 software and computer program of the sound compression system from manufacturers’ side. They are characterized by more better sound quality at lower bit rate. It allows recording the same CD-Audio formats using "lossy" or lossless compression algorithms in order to reduce the amount of data surface area at almost noticeable difference in the quality of the recording. To illustrate the problem, I have used the graphs of the spectrum and musical composition spectrograms. The comparison has been done on the basis of uncompressed music track from the original CD-Audio) lines before and after the abstract. This document is in the required format.
