The primary purpose of this paper is the improved detection of a nonstationary target signal embedded in a nonstationary background. Accordingly, the first part of the paper is devoted to a detailed exposition of how to deal with the issue of nonstationarity. The material presented here starts with Loève’s probabilistic theory of nonstationary processes. From this principled discussion, three i...

This paper presents a new characterization of musical signals which may lead to better understanding about how such signals are perceived. We first consider some signal analysis methods which facilitate measures of perceived qualities of music. More precisely, we consider a particular representation of signal energy on which to base a quantitative measure of sensory dissonance. After defining s...
