Claim 14:
15. A processor of an electronic device that is configured to:
retrieve, from memory of the electronic device, a spatial profile of an artificial sound source within a room in which the electronic device is located, wherein the spatial profile indicates a location of the artificial sound source within respect to the electronic device;
obtain a plurality of microphone signals from a microphone array of the electronic device that includes a segment of audio captured from within the room;
extract, using the plurality of microphone signals, one or more spatial features of the segment of audio;
determine whether the segment of audio originated at the location of the artificial sound source based on a comparison of the one or more spatial features and the spatial profile;
responsive to a determination that the segment of audio originated at the location, output a first notification indicating that an artificial sound event has occurred in the room; and
responsive to a determination that the segment of audio did not originate at the location, output a second notification indicating that a live sound event has occurred in the room.
