1. An audio device comprising:
a speaker;
a plurality of microphones; and
a controller configured to:
control the plurality of microphones to receive audio output from an external audio device,
determine an angle between the audio device and the external audio device, based on a phase difference between the audio received by the plurality of microphones,
calculate a ratio between magnitudes of the audio received by the plurality of microphones,
determine a distance between the audio device and the external audio device, based on a regression equation corresponding to the determined angle and the calculated ratio, and
adjust a setting for an audio output from at least one of the external audio device and the speaker, based on the determined angle and the determined distance.
