A Study on Pitch Detection in Time-Frequency Hybrid Domain
نویسندگان
چکیده
In this paper, we proposed a new method that can improve the accuracy of cepstrum pitch detection and can reduce the processing time. We control the phase information of cepstrum for making the pitch peak maximum. So we extract the exact pitch period easily. We shorten the processing time by omitting the bit-reversing process from the FFT and IFFT computation.

Newborn EEG Seizure Detection Based on Interspike Space Distribution in the Time-Frequency Domain
This paper presents a new time-frequency based EEG seizure detection method. This method uses the distribution of interspike intervals as a criterion for discriminating between seizure and nonseizure activities. To detect spikes in the EEG, the signal is mapped into the time-frequency domain. The high instantaneous energy of spikes is reflected as a localized energy in time-frequency domain. Hi...

The rotating machinery is a common class of machinery in the industry. The root cause of faults in the rotating machinery is often faulty rolling element bearings. This paper presents a novel technique using artificial neural network learning for automated diagnosis of localized faults in rolling element bearings. The inputs of this technique are a number of features (harmmean and median), whic...
متن کاملClassification of Iranian Traditional Music Dastgahs Using Features Based on Pitch Frequency
The Iranian traditional music is composed of seven majors Dastgahs: Chahargah, Homayoun, Mahour, Segah, Shour, Nava, and Rast-Panjgah. In this paper, a new algorithm for the classification of the Iranian traditional music Dastgahs based on pitch frequency is proposed. In this algorithm, the features of Lagrange coefficients of pitch logarithm (LCPL), Fuzzy similarity sets type 2 (FSST2), and th...
متن کاملOn the Detection of Melodic Pitch in a Percussive Background*
The extraction of pitch (or fundamental frequency) information from polyphonic audio signals remains a challenging problem. The specific case of detecting the pitch of a melodic instrument playing in a percussive background is presented. Time-domain pitch detection algorithms based on a temporal autocorrelation model, including the Meddis–Hewitt algorithm, are considered. The temporal and spect...
