Statistical, spectral and stochastic characteristics of music

The goal of this paper is to explore some of the principal spectral and statistical characteristics of music that are relevant to the problem of Blind Source Separation (BSS). Some BSS algorithms require some a priori knowledge of statistical characteristics of the mixtures under examination, if only to more accurately establish initial estimates. Furthermore, theoretical investigations depend upon the assumption of Wide-Sense Stationarity - the extent to which this assumption holds is investigated.
