Document Type and Number:
WIPO Patent Application WO/2020/155976
Kind Code:
A1
Abstract:
An audio signal processing method and apparatus. The method comprises: collecting audio signals satisfying a screening condition at the listening position (S403), wherein the screening condition comprises one or more of the following conditions: the volume at the listening position is greater than or equal to a volume threshold, or the listening distance between a sound source and the listening position is less than or equal to a preset listening distance, or the sound source is within the range corresponding to the listening orientation; encoding the collected audio signals to obtain encoded audio signals (S404); and sending the encoded audio signals to a decoding end (S405). The method can reduce the power consumption of decoding under the premise of ensuring the quality of the audio signals.
