The quantization effect on audio signals for wildlife intruder detection systems

Abstract

In this paper we present the influence of quantization of audio signals on D and S descriptors. These descriptors represent the number of samples between two consecutive real zeros and the number of points of local minima/maxima between two successive real zeros, respectively. It is shown that the number of the D/S pairs is almost constant and the behavior is almost the same till the number of bits is less than 6, in the proposed audio based wildlife intruder detection framework.
