Methods, apparatus, systems, and articles of manufacture to determine a location of an audio source are disclosed. Disclosed example apparatus are to determine respective error values for corresponding ones of a first dataset of time difference of arrival (TDOA) distance values between pairs of acoustic sensors, the error values based on a cost function, a first set of constraints and a second set of constraints. Disclosed example apparatus are also to adjust the corresponding ones of the first dataset of TDOA distance values based on the respective error values to determine a second dataset of TDOA distance values. Disclosed example apparatus are further to output the second dataset of TDOA distance values to source location circuitry that is to determine the location of the audio source.

Methods and apparatus to adjust time difference of arrival distance values used for source localization

Methods, apparatus, systems, and articles of manufacture to determine a physical location of an audio source are disclosed. One such apparatus includes a microphone set identifier to identify ordered microphone sets from a plurality of microphones and an estimated source location calculator to calculate estimated source locations for the audio source. The apparatus further includes an estimation error calculator to calculate respective estimation errors for corresponding ones of the estimated source locations. A likelihood calculator calculates respective likelihood values for corresponding ones of the estimated source locations and a first one of the estimated source location associated with a selected one of the likelihood values is used to represent the physical location of the audio source.
