  • receiving a transmission having sound data and an audio source spatial data set relative to the one or more microphones;

    determining, in a sound conditioning filter database having filters characterized by a stored set of coefficients wherein each stored set of filter coefficients is a function of at least one element of the audio source spatial data set, two or more stored sets of coefficients proximate to the at least one element of the audio source spatial data set;

    interpolating between the determined two or more stored sets of coefficients;

    convolving the sound data with a shaping filter having the interpolated filter coefficients; and

    transmitting the resulting signal to a sound-producing array.
