Abstract: The present disclosure relates to the field of audio signal processing, and to an audio signal rendering method and apparatus, and an electronic device. The rendering method includes: estimating a reverberation time of an audio signal on each time point among a plurality of time points; and performing rendering processing on the audio signal according to the reverberation time of the audio signal.

Abstract: The present invention relates to an audio rendering system and method and an electronic apparatus. The audio rendering system comprises: an audio signal encoding module, configured to for an audio signal in a specific audio content format, performing spatial encoding on the audio signal in the specific audio content format on the basis of metadata related information associated with the audio signal in the specific audio content format to obtain an encoded audio signal; and an audio signal decoding module, configured to performing spatial decoding on the encoded audio signal to obtain a decoded audio signal for audio rendering.

Abstract: An audio rendering system and method and an electronic apparatus. Provided is an audio coding method for audio rendering. The method includes: an acquisition step, which is used for acquiring an audio signal in a specific audio content format, and metadata-related information associated with the audio signal in the specific audio content format; and a coding step, which is used for performing, on the basis of the metadata-related information associated with the audio signal in the specific audio content format, spatial coding on the audio signal in the specific audio content format, so as to obtain a coded audio signal.

Abstract: The embodiments of the present disclosure disclose a method and device for processing an audio signal. A specific embodiment of the method includes acquiring a head image of a target user and an audio signal to be processed; determining head attitude angles of the target user based on the head image, and determining a distance between a target sound source and the head of the target user; and inputting the head attitude angles, the distance and the audio signal to be processed into a preset head related transfer function to obtain a processed left channel audio signal and a processed right channel audio signal, wherein the head related transfer function is used to characterize a correspondence between the head attitude angles, the distance and the audio signal to be processed, and the processed left channel audio signal and the processed right channel audio signal.
