Sound: To Pitch...

A hidden command that creates a Pitch object from every selected Sound object.

## Purpose

to perform a pitch analysis, optimized for speech.

## Settings

The settings that control the recruitment of the candidates are:

Time step (s) (standard value: 0.0)
  the measurement interval (frame duration), in seconds. If you supply 0.0, Praat will use a time step of 0.75 / (pitch floor), e.g. 0.01 seconds if the pitch floor is 75 Hz; in this example, Praat computes 100 pitch values per second.
Pitch floor (Hz) (standard value: 75 Hz)
  candidates below this frequency will not be recruited. This parameter determines the length of the analysis window: it will be 3 longest periods long, i.e., if the pitch floor is 75 Hz, the window will be 3/75 = 0.04 seconds long.

Note that if you set the time step to zero, the analysis windows for consecutive measurements will overlap appreciably: Praat will always compute 4 pitch values within one window length, i.e., the degree of oversampling is 4.

Pitch ceiling (Hz) (standard value: 600 Hz)
  candidates above this frequency will be ignored.

## Algorithm

This is the algorithm described at Sound: To Pitch (raw autocorrelation)..., with all the parameters not mentioned above set to their standard values.
