Sony patents audio system that adjusts sound levels based on masking

Sony has filed a patent for a system that analyzes incoming audio to identify specific patterns where sounds overlap or interfere with each other. The system then automatically lowers the volume of certain audio channels to reduce this interference before outputting the sound.

Why it mattersThis could improve clarity in complex audio scenes, such as in video games or movies, by ensuring distinct sounds remain audible without manual adjustment.

In the filing’s own words

A system for dynamically mixing audio content, the system comprising: a receiving unit configured to receive input audio; an analysis unit configured to analyse the input audio to determine one or more masking patterns; an attenuation unit configured to attenuate one or more channels of the input audio in accordance with the one or more masking patterns, and an output unit configured to output attenuated audio.

What exactly they claim (claim 1)

1. A system for dynamically mixing audio content, the system comprising: a receiving unit configured to receive input audio; an analysis unit configured to analyse the input audio to determine one or more masking patterns; an attenuation unit configured to attenuate one or more channels of the input audio in accordance with the one or more masking patterns, and an output unit configured to output attenuated audio.
