Abstract

The invention discloses an audio processing method and device, and a storage medium and belongs to the voice technology field. The method comprises steps that a to-be-processed first audio is obtained; the fundamental frequency information, the frequency spectrum envelope information and a first excitation signal of the first audio are extracted; according to the fundamental frequency information,a target period signal is determined, and the peak of the target period signal is at the frequency doubling portion of the fundamental frequency indicated by the fundamental frequency information; the target period signal and the first excitation signal are superposed to obtain a second excitation signal; the second excitation signal and the frequency spectrum envelope information are synthesizedto obtain a second audio. The method is advantaged in that human voice sharpness of the first audio can be improved, noise amplification of the first audio is avoided, and audio quality after processing is improved.

Description

technical field [0001] The present invention relates to the technical field of speech, in particular to an audio processing method, device and storage medium. Background technique [0002] In practical applications, limited by the recording scene or equipment of the audio source, the audio generally includes not only the human voice, but also a certain degree of noise such as breath sound, environmental noise, or equipment noise, which makes the human voice in the audio unclear. In order to improve the clarity of the human voice in the audio, the audio needs to be processed. [0003] In the related art, an audio processing method is provided, including: acquiring the first audio to be processed, and then performing Fourier transform on the first audio to obtain the first frequency spectrum signal of the first audio in the frequency domain, and then according to the For the first spectrum signal, an equalizer is used to increase the energy of the mid-high frequency signal in...
