Module irregularity

source code

This script produces a measure of the irregularity of a waveform. It is zero if the waveform is precisely periodic. It is approximately 1 for white noise.

This is used as the aperiodicity measure in Kochanski, Coleman, Grabe and Rosner JASA 2005.

Function Details

fractional_step_range(initial, final, step=1)

source code 

Generates an array of window offsets. No two offsets are equal, and they are integers between initial and final.
