Pitch...

Calculation Method

Cepstral Uses cepstral method for pitch extraction

Autocorrelation Uses autocorrelation for pitch extraction

Window length (ms) Sets the window length for pitch calculation. It should be lowered for female or children speakers with higher pitch values and increased for male with lower pitch values.

Step size (ms) Sets the how often the pitch values are reported.

Frequency Deviation Sets the pitch interval between adjacent points that is permitted. The program examines each pitch point, and if it differs from its immediate neighbors by more than the frequency deviation, then it is not reported.

Tracking Threshold Determines the level, at which the pitch-tracking algorithm starts looking for a fundamental frequency, since the pitch algorithm operates only when the voicing is above a certain threshold. The default is that the intensity of the signal must be at least 2% of the maximum intensity. If the background is very noisy it is advisable to make this threshold a somewhat larger number.

Calculation Range is the range that the algorithm uses to calculate the pitch.

Display Range is the range that the algorithm uses to display the pitch.

Add frequency grid with spacing (Hz) Selects frequency grids to be displayed with the desired interval.

Add time grid with spacing (ms) Selects time grids to be displayed with the desired interval.

Add Audio Selects audio data to be displayed on top of the pitch.

Add Intensity Selects intensity data to be displayed on top of the pitch. (Intensity is calculated only in "Absolute" mode).

Print/BMP

Prints and saves the pitch data according to these parameters.
