Acoustic Signal Processing Based on the Short-Time Spectrum

Abstract

The frequency domain representation of a time signal afforded by the Fourier transform is a powerful tool in acoustic signal processing. The usefulness of this representation is rooted in the mechanisms of sound production and perception. Many sources of sound exhibit normal modes or natural frequencies of vibration, and can be described concisely in the frequency domain. The human auditory system performs frequency analysis early in the hearing process, so perception is often best described by frequency domain parameters.
