On the pitch of two-tone complexes.

The predictions of two models for the pitch of two-tone complexes were compared to pitch matching results obtained in a previous study [Feth, O'Malley, and Ramsey, J. Acoust. Soc. Am. 72, 1403-1412 (1982)] and the present study. In one model, the pitch value of a waveform was calculated from the envelope-weighted average of instantaneous frequency of the waveform (the EWAIF model). In the other model, the pitch value was calculated from the squared-envelope-weighted average of instantaneous frequency (the SEWAIF model). The SEWAIF model better predicts the data.
