Process for adjusting the sound volume of a digital sound recording
First Claim
1. 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, andcalculating 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.

Abstract
The present invention relates to a process for adjusting the sound volume of a digital sound recording characterized in that it comprises: a step consisting of determining, in absolute values, for a recording, the maximum amplitude values for sound frequencies audible for the human ear, a step consisting of calculating the possible gain for a specified sound level setting, between the maximum amplitude value determined above and the maximum amplitude value for all frequencies combined, a step consisting of reproducing the recording with a sound card by automatically adjusting the amplification gain level making it possible to obtain a sound level for the recording of a specified value so that it corresponds to the gain calculated for this recording.

17. A method of reproducing audio via an audiovisual reproduction system, the method comprising:
-
reproducing, in connection with a processor of the audiovisual reproduction system, a recording while also, in connection with the processor, accounting for a specified gain for low-pitched and/or high-pitched sounds in the recording, the specified gain corresponding approximately to a specified volume attenuation of the recording to be assigned during the reproduction of the recording to evaluate amplifier input gain, the specified gain being increased, when possible, without exceeding a sound level selected by the user and without exceeding a maximum gain set for low-pitched and/or high-pitched sounds. - View Dependent Claims (18)
