Description

technical field [0001] The embodiments of the present disclosure relate to the field of computer technology, and in particular to an audio noise reduction transmission method, device, electronic equipment, and computer-readable medium. Background technique [0002] With the rapid development of electronic technology, earphones are widely used in the field of wearable devices. For example, earphones are widely used in the field of food delivery. When riders deliver food, they can communicate through earphones. At present, a single microphone is usually used to realize the noise-reduced transmission of the voice in the earphone. [0003] However, when the above method is adopted, the following technical problems usually exist: [0004] First, the audio itself is not subjected to noise reduction processing, resulting in poor noise suppression and reducing the efficiency of earphone transmission audio; [0005] Second, the influence of each amplitude and each phase included i...

Problems solved by technology

[0004] First, the audio itself is not subjected to noise reduction processing, resulting in poor noise suppression and reducing the efficiency of earphone transmission audio;

[0005] Second, the influence of each amplitude and each phase included in the time-domain waveform corresponding to the audio signal on audio noise reduction is not considered, which further leads to poor noise suppression effect;

[0006] Third, the voice transmission is not compressed, resulting in excessive communication bandwidth occupation, resulting in a low code rate for voice communication transmission
