1. A system comprising:

  • one or more processors;

    a first microphone array comprising a first plurality of microphones in a first arrangement, the first plurality of microphones being coupled to the one or more processors and configured to generate first signal data from a sound source;

    a second microphone array comprising a second plurality of microphones in a second arrangement, the second plurality of microphones being coupled to the one or more processors and configured to generate second signal data from the sound source;

    a localization module executable by the one or more processors to;

    determine a first spatial location of the sound source based at least in part on the first signal data, the first spatial location of the sound source being calculated as a distance from an origin; and

    based at least in part on a determination that the distance from the origin is below a threshold value, determine a second spatial location of the sound source based at least in part on the second signal data.
