Abstract
The present invention relates to a method for estimating a pattern, in particular a pitch and/or a fundamental frequency, in a signal having a periodic, quasiperiodic or virtually periodic component, wherein the signal is transformed from a time-domain to a frequency-domain to obtain a spectrum of the signal, the spectrum is processed to obtain a zero-phase spectrum of the signal, the spectrum of the signal is transformed to the time-domain to obtain a correlation signal, the spectrum and the correlation signals are combined to a combined spectrum, and the pattern is estimated on the basis of the combined spectrum.
