Abstract
The present invention relates to a process for adjusting the sound volume of a digital sound recording characterised 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.

8. Process for adjusting the sound volume of a digital sound recording, 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, 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.

10. Volume adjustment devices, characterised in that it comprises dynamic adjustment means for the reproduction sound levels of the recording, accounting for a specified gain for the low-pitched and/or high-pitched sounds in the recording and the gain corresponding approximately to the specified attenuation to be assigned during the reproduction of the recording to evaluate the amplifier input gain.
