Abstract

A simple scheme for compressing sparse representation of melodic music is outlined. The method is designed to store the output of sparse approximation (SA) of that class of signals. Sparsity is achieved using a trigonometric dictionary and a dedicated greedy strategy aiming at approximating the signal at the good point-wise quality. Comparisons to the popular MP3 standard illustrate the suitability of the scheme for storing, in a small file, SA of melodic music.
