SYSTEM, METHOD AND COMPUTER PROGRAM FOR ANALYSING AN AUDIO SIGNAL

摘要

A device for analyzing an audio signal to obtain an analysis representation of the audio signal includes a converter for converting the audio signal into a representation representing a neurotransmitter vesicle occurrence in clefts between a plurality of nerve fibers and inner auditory cells of an ear model, and a calculator for calculating a neural activity pattern over time on the plurality of nerve fibers, which results based on the neurotransmitter vesicle occurrence, wherein the neural activity pattern is an analysis representation of the audio signal. The inventive device thus generates an especially suitable analysis representation of an audio signal in which masking effects occurring in the generation of action potentials on nerve fibers are considered. The inventive analysis representation is also suitable for an examination of the audio content and also for controlling cochlea implants.
