For Pitch Extraction
A synthesis-based method for pitch extraction of the speech signal is proposed. The method synthesizes a numb¢: of log power spectra for different values of fundamental frequency and compares them with the log power spectrum of the input speech segment. The average magnitude (AM) difference between the two spectra is used for comparison. The value of fundamental frequency that gives the minimum...
متن کاملVirtual Pitch Extraction from Harmonic Structures by Absolute Pitch Musicians1
The ability of absolute pitch (AP) musicians to identify or produce virtual pitch from harmonic structures without feedback or an external acoustic referent was examined in three experiments. Stimuli con sisted of pure tones, missing fundamental harmonic complexes, or piano notes highpass filtered to remove their fundamental frequency and lower harmonics. Results of Experiment I showed that rel...
متن کاملDisinhibition in pitch memory
Recognition of the pitch of a tone is disrupted by the interpolation of other tones during the retention interval. The disruptive effect of an interpolated tone varies systematically as a function of its pitch relationship to the tone to be remembered, and is maximal at a ⁄3-tone separation. When such a tone is interpolated, the interpolation in addition of a further tone that is ⁄3 tone remove...
متن کاملA pitch determination algorithm based on subharmonic-to-harmonic ratio
In the present paper, a pitch determination algorithm (PDA) based on Subharmonic-to-Harmonic Ratio (SHR) is proposed. The algorithm is motivated by the results of a recent study on the perceived pitch of alternate pulse cycles in speech [1]. The algorithm employs a logarithmic frequency scale and a spectrum shifting technique to obtain the amplitude summation of harmonics and subharmonics, resp...
متن کاملMeasuring inharmonicity through pitch extraction
Some experiments are described which illustrate new applications of pitch extraction processing. It is shown that cepstrum and harmonic product spectrum contain distinctive information about the inharmonicity of musical sounds in this case piano tones and that they can be successfully used for illustration of the phenomenon. A way is proposed how to improve the methods, enabling a direct quanti...
