Abstract

Possibilities and advantages of the audio data compression with the application of wavelet-transformations are considered in the article. Problems of the existing sound compression methods are revealed, ways of wavelets introduction into algorithms of compression are analyzed, the scheme of compression of the audio data on the basis of adaptive orthogonal transformations is offered.

Keywords: audio compression, codec, coding, wavelet transform, MPEG
