Abstract

The embodiment of the invention provides an audio signal correction method and device, a storage medium and an electronic device, and the method comprises the steps: determining a first audio signal obtained through the collection of a target audio signal by reference pickup equipment; determining a second audio signal obtained by collecting the target audio signal by the to-be-corrected pickup device; determining a target correction value based on a first distance between playing sources of the first audio signal, the second audio signal, and the target audio signal and the reference pickup device, and a second distance between the playing source and the to-be-corrected pickup device; and correcting other audio signals subsequently acquired by the to-be-corrected pickup device based on the target correction value. According to the invention, the problem that audio signal correction is inaccurate in the prior art is solved, and the audio signal correction accuracy is improved.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, relate to an audio signal correction method, device, storage medium, and electronic device. Background technique [0002] Currently, microphone arrays are widely used in smart home appliances. To realize human-computer interaction, microphone signal processing must be performed first. Among them, sound source localization and beamforming require the correct amplitude and phase relationship between the channels of the microphone. In many cases, problems such as inconsistency between the microphone structure and hardware will result in inaccurate sound source localization based on the collected signal, and the direction cannot be eliminated through beamforming. Sexual interference, therefore, microphone signal correction is necessary. [0003] In related technologies, the main method of conventional microphone calibration is to place a sound source at a certain di...
