摘要
PURPOSE: A pitch estimating system using an interpolation method in a time-frequency mixing domain is provided to use the interpolation method when a time domain is mixed with a frequency domain. CONSTITUTION: A second autocorrelator(520) outputs an autocorrelated value of a frequency domain. A first interpolator interpolates an autocorrelated value of a time domain. A second interpolator interpolates the autocorrelated value of the frequency domain. A pitch estimator(540) applies a weighted value to the interpolated autocorrelated value of the time domain and the interpolated autocorrelated value of the frequency domain. The pitch estimator estimates a final pitch.
