1. A method for localizing audio devices in an audio environment, the method comprising:
obtaining, by a control system, direction of arrival (DOA) data corresponding to sound emitted by at least a first smart audio device of the audio environment, the first smart audio device including a first audio transmitter and a first audio receiver, the DOA data corresponding to sound received by at least a second smart audio device of the audio environment, the second smart audio device including a second audio transmitter and a second audio receiver, the DOA data also corresponding to sound emitted by at least the second smart audio device and received by at least the first smart audio device;
receiving, by the control system, configuration parameters, the configuration parameters corresponding to the audio environment, corresponding to one or more audio devices of the audio environment, or corresponding to both the audio environment and the one or more audio devices of the audio environment; and
minimizing, by the control system, a cost function based at least in part on the DOA data and the configuration parameters, to estimate a position and an orientation of at least the first smart audio device and the second smart audio device.
