1. A sound system comprising:

  • a space defined by a structure;

    a plurality of audio microphones and a plurality of audio speakers, said plurality of audio microphones and said plurality of audio speakers positioned within said structure;

    at least one processor, the processor comprising at least one digital signal processor (DSP), wherein the processor controls delays and power delivery of sounds propagating in said space from said plurality of audio speakers;

    a plurality of first digital bit streams, said plurality of first digital bit streams associated with first outputs of said plurality of audio microphones, said first outputs of said plurality of audio microphones responsive to first sounds emanating from a first location;

    wherein said processor correlates a first time difference of arrival of said plurality of first digital bit streams and a first measured power levels of said plurality of first digital bit streams from said plurality of audio microphones;

    wherein said processor determines from said first time difference of arrival and said first measured power levels of said plurality of first digital bit streams a first position in said space of said first location;

    wherein said processor determines a first proper settings of time differences and power levels for a plurality of first returning digital bit streams sent to said plurality of audio speakers, said plurality of first returning digital bit streams being coupled to amplifiers that are coupled to said plurality of audio speakers, said amplifiers set to said first proper settings of power levels to account for distances between said plurality of audio speakers and said first location, the application of said plurality of first returning digital bit streams to said plurality of audio speakers being timed to said first proper settings of time differences to generate a first reinforced audio signal delivered to said first location in said space;

    a plurality of second digital bit streams, said plurality of second digital bit streams being associated with second outputs of said plurality of audio microphones, said second outputs of said plurality of audio microphones responsive to second sounds emanating from a second location;

    wherein said processor correlates a second time difference of arrival of said plurality of second digital bit streams and a second measured power levels of said plurality of second digital bit streams from said plurality of audio microphones;

    wherein said processor determines from said second time difference of arrival and said second measured power levels of said plurality of second digital bit streams a second position in said space of said second location; and

    wherein said processor determines a second proper settings of time differences and power levels for a plurality of second returning digital bit streams sent to said plurality of audio speakers, said plurality of second returning digital bit streams being coupled to said amplifiers that are coupled to said plurality of audio speakers, said amplifiers set to said second proper settings of power levels to account for distances between said plurality of audio speakers and said second location, the application of said plurality of second returning digital bit streams to said plurality of audio speakers being timed to said second proper settings of time differences to generate a second reinforced audio signal delivered to said second location in said space.
