The accuracies of four pitch extraction methods are introduced and compared for high‐precision perturbation measurement. They include combinations of peak‐picking, zero‐crossing, and waveform‐matching strategies. The effects of sampling frequency, signal‐to‐noise ratio, pitch frequency, and signal modulation on the accuracies are explored. It is shown that methods with the waveform‐matching technique give the best results for most cases. For near‐sinusoidal stimuli (e.g., EGG signals), the zero‐crossing technique gives higher accuracy than the peak‐picking technique. At a low signal‐to‐noise ratio, a higher sampling frequency does give better results for the waveform‐matching technique, but the accuracy of the peak‐picking method may reduce as sampling frequency increases. As the signal‐to‐noise ratio increases, the effect of sampling frequency on accuracy diminishes when interpolation is used. A variety of waveforms are currently being tested to check the suitability of these methods for different applications. [Work supported by NIH.]
