Abstract:
The embodiments of the present invention disclose an audio processing method and apparatus, an electronic device, a storage medium, and a program product; the method comprises: obtaining from each of at least two external loudspeakers an audio signal to be played, and a target source source angle corresponding to each audio signal to be played; determining a signal transmission angle between each external loudspeaker and the head of a user, and based on the signal transmission angle and the target sound source angle, calculating an anti-crosstalk function corresponding to the signal transmission angle, the anti-crosstalk function being used for eliminating crosstalk generated by the at least two external loudspeakers when playing audio externally; based on the target sound source angle, the signal transmission angle, and the anti-crosstalk function, performing signal transformation on the audio signals to be processed of each external loudspeaker, to obtain target playback audio signals corresponding to audio signals to be played. The invention allows for generating an audio signal capable of representing the orientation of a sound source, and allows for eliminating crosstalk generated when external loudspeakers are used for playing audio, allowing a user to enjoy audio having a better playback effect.
