Short-time power spectra: Estimation and acoustical applications

1983
The study deals with the theoretical background and practical acoustical applications of the short-time FFT frequency analysis. The fundamental concept of the instantaneous spectrum is reviewed. Its practical estimation by the lagged window FFT and the straightforward extension to two-channel signals and cross-spectra are presented.
