Abstract: Provided are an audio processing method and apparatus, and a storage medium, which relate to the technical field of artificial intelligence and, in particular, to the speech technical field. The specific implementation solution is as follows. In response to receiving to-be-processed audio, a target sounding direction corresponding to the to-be-processed audio is determined; direction sense reconstruction is performed on the to-be-processed audio according to a direction sense reconstruction filter corresponding to the target sounding direction to obtain target audio; and the target audio is output.

Abstract: A speech enhancement method includes steps as follows. Subband decomposition processing is performed on at least two paths of target speech to obtain amplitude spectrums and phase spectrums of the at least two paths of target speech, where the at least two paths of target speech include: target mixed speech and target interference speech; a prediction probability of the target mixed speech including target clean speech in a feature domain is determined according to the amplitude spectrums of the at least two paths of target speech; and subband synthesis processing is performed according to the prediction probability and the amplitude spectrums and the phase spectrums of the at least two paths of target speech to obtain the target clean speech in the target mixed speech.
