Title:
SOUND SOURCE LOCALIZATION-BASED AUDIO PLAYBACK METHOD, AUDIO PLAYBACK APPARATUSES, PROJECTION DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/052529
Kind Code:
A1
Abstract:
A sound source localization-based audio playback method, audio playback apparatuses, a projection device, and a medium, relating to the field of audio playback. The sound source localization-based audio playback method comprises: sequentially playing back audio data of channels, obtaining, by means of a microphone array, sound emitted by sound boxes corresponding to the channels, and measuring and calculating spatial positions of the sound boxes corresponding to the channels (S101); determining relative positions among the sound boxes according to the spatial positions of the sound boxes (S102); and setting an audio stream data format according to the relative positions among the sound boxes (S103). The audio stream data format is set according to the positions of the sound boxes, so that the audio stream data format conforms to a sound box placement position of a user, even if the user places the sound box wrongly, the position of the sound box does not need to be readjusted, and the original effect of a multi-channel sound box system can also be achieved or basically achieved. Moreover, according to the positions of the sound boxes, sending time of corresponding sound box data in the audio stream data format is changed, synchronization of the audio data is ensured, and the user experience is improved.
