Abstract

La presente invenzione si riferisce ad un metodo e ad un sistema psicoacustico per la codifica del segnale audio che sfrutta le caratteristiche percettive del sistema uditivo umano.In particolare, il sistema si basa su un metodo di analisi che permette di evidenziare le caratteristiche del segnale audio che risultino essere percettivamente significative.Tale informazione, secondo un aspetto del trovato, può essere sfruttata per comprimere l'informazione contenuta nel suddetto segnale allo scopo di poterla trasmettere in modo efficiente.The present invention refers to a method and a psychoacoustic system for the coding of the audio signal that exploits the perceptive characteristics of the human auditory system. In particular, the system is based on an analysis method that allows to highlight the characteristics of the audio signal. which are perceptually significant.This information, according to an aspect of the invention, can be used to compress the information contained in the aforementioned signal in order to be able to transmit it efficiently.
