Embodiment Construction

[0061] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0062] figure 1 It is a flowchart of an audio signal processing method provided by an embodiment of the present invention, see figure 1 , The method can include the following steps:

[0063] 101. The electronic device acquires at least one first short-term frequency spectrum signal of the first audio signal.

[0064] 102. The electronic device acquires a periodic signal in the frequency domain, and the period of the periodic signal in the frequency domain is used to indicate the pitch frequency of the periodic signal.

[0065] 103. The electronic device obtains at least one second short-term frequency spectrum signal based on the periodic signal and the at least one first short-term frequency spectrum signal, and the pitch frequency of each second ...

Abstract

The invention discloses a method and a device for audio signal processing, an electronic device and a storage medium, and belongs to the technical field of computers. The method includes: acquiring atleast one first short-time spectrum signal of the first audio signal; acquiring a periodic signal in the frequency domain, wherein a period of the periodic signal in the frequency domain is used to represent a pitch frequency of the periodic signal; and based on the periodic signal and at least one a short time spectrum signal, obtained at least one second short time spectrum signal, the fundamental frequency of each second short time spectrum signal being the same as the fundamental frequency of the periodic signal; and the second audio signal is obtained based on the at least one second short time spectrum signal The pitch frequency of the second audio signal is the same as the pitch frequency of the periodic signal. The pitch frequency of the second audio signal obtained by the invention is fixed, the pitch is always stable, the sound effect of "alien" is generated, and the sound characteristics in the first audio signal are retained, and the distortion rate is low, It is difficultto understand or understand when playing.

Description

Technical field [0001] The present invention relates to the field of computer technology, and in particular to an audio signal processing method, device, electronic equipment and storage medium. Background technique [0002] With the development of computer technology and the diversification of terminal functions, people can record through the terminal, and use audio signal processing methods to transpose the recording to produce a variety of sound effects. For example, the "alien" sound effect. People can record on the terminal, and process the recording through the operation on the terminal, thereby creating an abnormal sense of pronunciation and hearing, so that it sounds like it is not a human voice, but the voice of a robot or an alien Human voice. [0003] At present, the audio signal processing method is usually through effects, reverberation or adding background sound, by changing the timbre of the audio signal, modulating or delaying the phase of the sound wave, or enhan...
