Embodiment Construction

[0074] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0075] figure 1 It is a schematic flowchart of an audio processing method provided in the embodiment of the present application. The method can be used with computer equipment. Such as figure 1 As shown, the method includes:

[0076] Step 101, using cepstrum technology to determine the fundamental frequency and resonance frequency in the original audio frame.

[0077] Step 102: Use a notch filter to filter out the signal corresponding to the fundamental frequency and the signal corresponding to the resonance frequency from the original audio frame to obtain noise in the original audio frame.

[0078] Wherein, the signal corresponding to the fundamental frequency is the fundamental signal, and the signal corresponding to the r...

Abstract

The invention discloses an audio processing method and device and a computer storage medium, and belongs to the technical field of electronics. The method comprises the following steps: determining afundamental frequency and a resonant frequency in an original audio frame by adopting a cepstrum technology; and filtering a signal corresponding to the fundamental frequency and a signal corresponding to the resonant frequency from the original audio frame by adopting a notch filter to obtain noise in the original audio frame; and then removing noise in the original audio frame to obtain a targetaudio frame. Because the voice signal comprises the signal corresponding to the fundamental frequency and the signal corresponding to the resonant frequency, the noise removed from the original audioframe is the signal except the voice signal in the original audio frame, and the obtained target audio frame is the pure voice signal. According to the embodiment of the invention, the noise in the audio is reduced by filtering the noise in the original audio frame, the fidelity of the voice in the audio can be ensured, and the audio processing effect is further ensured.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to an audio processing method and device, and a computer storage medium. Background technique [0002] In the multimedia field, audio recording is a very basic function. Recorded audio is often used for communication, human-computer voice interaction, song production, etc. [0003] When recording a song in a recording studio, since professional microphones and other voice recording equipment are usually used, the quality of the recorded audio is relatively high. However, in scenarios such as mobile communications, man-machine voice interaction, and karaoke entertainment, the performance cannot be compared with professional voice recording equipment due to the cost and volume of voice recording equipment (usually mobile phones, etc.), and users are recording The surrounding environment cannot be guaranteed to be completely quiet during audio, so the recorded audio gen...
