Webb21 maj 2024 · We can thus expect to see a peak in the cepstrum at the quefrency corresponding to the pitch-period length (in seconds). If we assume that fundamental frequencies F 0 are in the range 80 to 450 Hz, then the corresponding peak in the cepstrum should lie at quefrency 1/F 0 and they range from 2.2 to 12.5 milliseconds. Webba mean frequency of 415 Hz. INTRODUCTION Vocal register is a highly relevant aspect of the singing voice, but its nature has remained unclear in the sense that many terms and definitions exist. Register has been defined as a "group of like sounds or tone qualities whose origins can be traced to a special kind of ...

If Young's modulus increases in the 45°, 135°, 225° and 315° directions by 20% (correspondingly, e 4 decreases about 70%), the frequency split will be reduced to 174 Hz.
