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: A mounting device for directly bonding brackets to the tooth surface includes a tray and a mounting rack. Each mounting rack is used for mounting a bracket, and the mounting rack includes a support and a positioning clamp. The tray is used as the support base for installing the mounting rack. The support is used as the fixed supporting part, with one end connected and fixed to the lingual or lip side of the tray. The positioning clamp is used as the rotating part to connect with the bracket and adjust the position of the bracket. The positioning clamp includes a damping rotation shaft, the damping rotation shaft matches with the support, the positioning clamp rotates around the support through the damping rotation shaft, and the support and the tray adopt an integrally formed structure or detachable structure.
