Acoustical Signals of Passalid Beetles: Complex Repertoires

Adult passalids produced sounds of 7 basic structural types in at least 13 different behavioral contexts. A given type in a particular behavioral context may be termed a "signal". A total of 31 signals were recorded from 57 species. The presence of the same basic signals in both New World tribes suggests an early origin of the fundamental repertoire. The 14-signal repertoire of Odontotaenius di...

Some Aspects of Analysis of Dolphins’ Acoustical Signals

Dolphins produce various types of sounds in a wide range of frequencies. Characteristics of some sounds till now have not been correctly registered, that influenced on interpretation of their functions. Studying of the characteristics and functions of dolphins’ acoustical signals is the purpose of the present work. In this work the acoustical signals of two dolphins (Tursiops truncatus) were re...

Processing of acoustical signals via a wavelet-based analysis

In the present paper, details are given on the implementation of a wavelet-based analysis tailored to the processing of acoustical signals. The family of the suitable wavelets (‘Reimann wavelets’) are obtained in the time domain from a Fourier transform, extracted in Ref. [6] after invoking theoretical principles and time-frequency localisation constraints. A scheme is set forth to determine th...

Common Acoustical Pole Estimation from Multi-Channel Musical Audio Signals

This paper describes a method for estimating the amplitude characteristics of poles common to multiple room transfer functions from musical audio signals received by multiple microphones. Knowledge of these pole characteristics would make it easier to manipulate audio equalizers, since they correspond to the room resonance. It has been proven that an estimate of the poles can be calculated prec...

Sparse Representation of Multiple Signals

We discuss the problem of nding sparse representations of a class of signals. We formalize the problem and prove it is NP-complete both in the case of a single signal and that of multiple ones. Next we develop a simple approximation method to the problem and we show experimental results using arti cially generated signals. Furthermore,we use our approximation method to nd sparse representations...
