The invention discloses an audio processing method and device, an electronic device and a storage medium and belongs to the technical field of audio processing. The audio processing method comprises the steps that filtering processing is conducted on audios through multiple filters to obtain low-frequency audios, intermediate-frequency audios and first high-frequency audios, wherein the frequencyof the intermediate-frequency audios is in a human sound frequency range, the maximum frequency of the low-frequency audios is smaller than or equal to the minimum frequency of the intermediate-frequency audios, and the minimum frequency of the first high-frequency audios is greater than or equal to the maximum frequency of the intermediate-frequency audios; the low-frequency audios and the firsthigh-frequency audios are respectively delayed for preset time; the intermediate-frequency audios and the delayed low-frequency audios and first high-frequency audios are synthesized to obtain targetaudios. By adopting the audio processing method, the human sound definition of audios can be improved, it can be also ensured that the original balance degree of the audios is not destroyed, and original signal energy of the audios is not changed.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of audio processing, and in particular, to an audio processing method, device, electronic equipment, and storage medium. Background technique [0002] The core of audio such as songs is human voice (capella), but at present, people often do not listen to audio in a quiet environment, and most of them listen to it when they are exercising or taking a vehicle. In this case, the noise or The accompaniment will weaken or even cover up the vocal signal of the singer in the audio, causing users to be unable to hear the singer's singing content clearly and affecting the user experience. In order to make the human voice in the audio clearer, the audio needs to be processed accordingly. [0003] At present, an equalizer is generally used to enhance the human voice in the audio. In the implementation process, the audio to be processed can be Fourier transformed first to obtain the first spe...
