1. A method for adjusting the sound volume of a digital sound recording, the method comprising:
- determining, in absolute values, for a recording, the maximum amplitude values for sound frequencies audible for the human ear;
calculating the possible gain for a specified sound level setting, between the maximum amplitude value and the maximum amplitude value for all frequencies combined; and
reproducing the recording 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,wherein the reproduction step comprises a dynamic reproduction sound level adjustment step on the recording including authorizing 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 reproduction 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.

- 7. A volume adjustment device comprising dynamic adjustment means for the reproduction sound levels of a recording, accounting for a specified gain for the 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.
