Abstract
Various embodiments disclose a computer-implemented method comprising determining a target location in an environment, determining a set of sub-band impulse responses for a first frequency sub-band, each in the set of sub-band impulse responses being associated with a location proximate to the target location, selecting a first pair of sub-band impulse responses for the first frequency sub-band among pairs within the set of sub-band impulse responses, computing a first coherence value indicating a coherence level between sub-band impulse responses in the first pair, determining that the first coherence value is below a coherence threshold, in response, combining the sub-band impulse responses using a non-linear interpolation technique to generate an estimated impulse response for the first frequency sub-band for the target location, generating, based on the estimated impulse response, a filter for a speaker, filtering an audio signal, and causing the speaker to output the filtered audio signal.
