Problems solved by technology

[0003] Moreover, since it can only be deployed at a single point, if you want to cover a larger area, you need to deploy a large number of microphones with large apertures. As the number of microphones in the array system increases, the cost will rise rapidly, and the difficulty of space deployment will also increase. increases, and the robustness will decrease significantly

Abstract

Embodiments of the present application provide a method and device for processing audio data, electronic equipment, and a storage medium. The method includes: acquiring first multi-channel audio data; wherein, the first multi-channel audio data is generated by one or more microphone arrays The collected audio data is composed; the first multi-channel audio data is de-reverberated to obtain the second multi-channel audio data; the time-frequency mask for the second multi-channel audio data is generated; according to the time-frequency mask, the second The multi-channel audio data is subjected to beamforming processing to obtain first single-channel audio data; the first single-channel audio data is used to output an audio signal. Through the embodiment of the present application, the audio processing of asynchronously collected multiple microphone arrays is realized, which avoids the high cost caused by only using a synchronously collected unified array for audio processing, expands the sound pickup range, and improves robustness .

Description

technical field [0001] The present application relates to the field of audio data processing, in particular to an audio data processing method and device, electronic equipment, and a storage medium. Background technique [0002] At present, the microphone array technology usually focuses on the unified array system of synchronous acquisition, and the unified array system of synchronous acquisition has high requirements for hardware design, manufacture and deployment. [0003] Moreover, since it can only be deployed at a single point, to cover a larger area, it is necessary to deploy a large number of microphones with large apertures. As the number of microphones in the array system increases, the cost will rise rapidly, and the difficulty of space deployment will also increase. increases, and the robustness decreases significantly. Contents of the invention [0004] In view of the above problems, it is proposed to provide a method and device, an electronic device, and a s...
