Patent ID: 8873772

Claim:
An audiovisual reproduction system, comprising: processing resources including a processor and a memory; and a non-transitory computer readable storage medium tangibly storing a sound management program; wherein the sound management program, in connection with the processing resources, is configured to adjust the sound volume of a digital sound recording to be reproduced by the audiovisual reproduction system by at least: determining, in absolute values, for the recording, the maximum amplitude values for sound frequencies audible for the human ear, and calculating the possible gain (Gv) for a specified sound level setting, between the maximum amplitude value (A2) and the maximum amplitude value (Am) for all frequencies combined, the possible gain being determined by applying the following formula: Gv=20 log (A2/Am); wherein the sound recording is reproducible by the audiovisual reproduction system by at least automatically adjusting the amplification gain level so as to obtain a sound level of a specified value for the recording so that it corresponds to the gain calculated for the recording; and wherein a dynamic reproduction sound level adjustment is to be performed on the recording during reproduction so as to authorize a specified gain for the low-pitched and/or high-pitched sounds in the recording, the gain corresponding approximately to the attenuation applied during the production of the recording.
