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.
