Abstract
With regard to spectral representation of audio-signals such as speech and music, Fourier transformation is reconsidered in the framework of a simple concept of parametric signal representation. In the formula which specifies the complex coefficients of a Fourier series, the integration interval T is regarded as an analysis interval instead of the signal period. Thereby that formula gets the status of a basic and universal transformation which specifies the so-called Fourier-amplitude spectrum of that portion of a time signal which falls into the analysis interval.
