hist_entry Struct Reference

A histogram is an array of HIST_SIZE hist_entry storing all the energies recorded (with an accuracy of 1/HIST_GRAIN) of the loudnesses from ABS_THRES (at 0) to ABS_UP_THRES (at HIST_SIZE-1). More...

Detailed Description

A histogram is an array of HIST_SIZE hist_entry storing all the energies recorded (with an accuracy of 1/HIST_GRAIN) of the loudnesses from ABS_THRES (at 0) to ABS_UP_THRES (at HIST_SIZE-1).

This fixed-size system avoids the need of a list of energies growing infinitely over the time and is thus more scalable.
