METHOD AND SYSTEM FOR ENHANCING AN AUDIO SIGNAL

摘要

The invention relates to a method for enhancing an audio signal intended for being broadcast to at least one target listener, said method including the following steps: receiving an audio signal s(t); filtering (201) the audio signal s(t) by means of a frequency enhancement filter, the frequency template of which is determined from statistical values of auditory threshold deviation, as a function of the frequency, that are characteristic of said at least one target listener; normalising (203) the filtered signal, by a gain configured in accordance with said at least one target listener, such that said signal is between an absolute auditory threshold (SAA) and a pain threshold (SD); the absolute auditory threshold (SAA) being determined for a given listener profile.
