Innovations in musical signal processing - Overview

Since the introduction of neumatic notation in Gregorian chant, music has used a bidimensional representation of sounds to describe the distribution of frequency energy along a time axis. During the centuries this representation and the abstract conception of music that it suggests has further evolved. Musicians today naturally think about music in terms of the two parameters of time and frequency. Not surprisingly, Dennis Gabor and other researchers were inspired by this representation of music when they laid the foundations of modem time-frequency representations, which are now the main reference tools in the theory of signals and all its myriad applications.
