Audio processing apparatus and method for localizing an audio source The invention relates to an audio processing apparatus (400) for localizing an audio source. The audio processing apparatus (400) comprises a plurality of audio sensors (402i), including a primary audio sensor and at least two secondary audio sensors, configured to detect an audio signal from a target audio source, wherein the primary audio sensor defines at least two pairs of audio sensors with the at least two secondary audio sensors; and a processing circuitry. The processing circuitry is configured to: determine for each pair of audio sensors a first set of likelihoods of spatial directions of the target audio source using a first localization scheme; determine a second set of likelihoods of spatial directions of the target audio source using a second localization scheme; and determine a third set of likelihoods of spatial directions of the target audio source on the basis of the first sets of likelihoods and the second set of likelihoods. Moreover, the invention relates to a corresponding audio processing method.
