Music files compression based on time-frequency representation of audio signal
A.V. Shekhirev, E.V. Rabinovich · 2008
Audio data compression algorithm based on time-frequency presentation of music signal is offered. For calculation time-frequency representation of an audio signal was developed the algorithm, based on short fast Fourier transform (SFFT). The result of algorithm work are the files having as it is possible the smaller size on condition that ldquothe main senserdquo of music will keep, for tasks of identification of a signal, search of pieces of music, etc.
