Abstrakt

Artykuł ten opisuje sposób wykorzystania algorytmu ekstrakcji częstotliwości podstawowej sygnału opartego na analizie cepstrum do określenia wysokości pojedynczych dźwięków instrumentów muzycznych, a dokładniej - dźwięku fortepianu. Przedstawia szczegółowo tą metodę oraz wskazuje problemy związane z dokładnością tego algorytmu dla różnych wysokości dźwięku.

 

Abstract

This article describes how to use the algorithm for the extraction of fundamental frequency signal based on cepstrum analysis to determine the amount of the individual sounds of musical instruments, and more-the sound of the piano. Shows in detail the method and indicates problems with the accuracy of this algorithm for various.
