摘要
A method, apparatus, and computer program product are provided for encoding audio events as geo-referenced audio events for use in location establishment. Methods may include: receiving first audio data from a first sensor; establishing a baseline frequency profile; identifying, within the first audio data, a first audio event, where the first audio event satisfies at least one predefined criteria relative to the baseline frequency profile; identify a location corresponding to the first audio event; encoding the first audio event in a database to correspond to the location; receiving second audio data from a second sensor; identifying, within the second audio data, a second audio event; correlating the second audio event with the first audio event; and providing the location in response to the second audio data. The at least one criteria may include a statistically significant change in a prominent frequency in the audio data.
