This paper describes a wavelet-based perceptual audio coder, addressing the problem of
the search for the wavelet-packet decomposition that minimizes a new perceptual cost …

The time-varying discrete-time signal expansion was analysed based on the theory of time-
varying filter banks in detail. A general definition of time-varying discrete-time wavelet …

In this paper, a new algorithm for achieving flexible tiling of the time axis for audio coding
purposes is presented. It is based on the calculus of the distances among a predetermined …

Discrete-time wavelet transform (DWT) is found to be better than other transforms in the time-
varying system analysis, eg for time-varying parametric modelling [16], time-varying systems …

Blackboard modelling provides a great flexibility in structuring complex problems and a
robust adaptation to the conditions of the signal to be analyzed, adding both bottom-up and …

The application of the matching pursuit algorithm for extracting sinusoidal components and
transients from audio signals is proposed. The resulting residue is perceptually modelled as …

In this paper an efficient model which implements a multilevel structure of auditory
information will be presented. An exhaustive analysis of the input signal in both subjective …
