Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Mathematical model of spectral compression of the audio information B.Y. PARSHIN, D.O. ZHUKOV In work use of the spectral approach in questions of compression of the audio information is considered. In particular it is shown that use of discrete fast Fourier transform at an initial stage of splitting of an audio signal on the containing 1024 readout, allows to receive faster compression Key words: audio information, compression, spectral approach, fast Fourier transform, frame.
