Method, apparatus and computer-readable media utilizing positional information to derive AGC output parameters

Program code embodied in a non-transitory computer readable medium for automatic gain control utilizing sound source position information in a shared space having a plurality of microphones and a plurality of sound sources, said program comprising instructions causing at least one processor to:

• receive combined sound signals from the plurality of microphones;
• locate, using one or more processors, position information corresponding to each of the plurality of sound sources in the shared space;
• determine, using the one or more processors, the distance to each of the plurality of sound sources from each of the plurality of the microphones in the shared space, based on the position information;
• define, using the one or more processors, a predetermined gain weight adjustment for each of the plurality of microphones, based on the distance information;
• apply the defined plurality of gain weight adjustments to the plurality of microphones in order to control the gain of the desired plurality of sound sources in the shared space;
• maintain, using the one or more processors, a substantially constant ambient sound level regardless of the position of the plurality of sound sources and the applied gain weight adjustments to the plurality of microphones, based on the received signals from the plurality of microphones;
• and
• output, using the one or more processors, a summed signal of the plurality of sound sources at a derived gain with a constant ambient sound level across the plurality of sound source positions in the shared space.
