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 further described in detail below with reference to the accompanying drawings.

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

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

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

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

Abstract

The invention discloses an audio signal processing method, device, electronic equipment and storage medium, belonging to the technical field of computers. The method includes: acquiring at least one first short-time spectrum signal of the first audio signal; acquiring a periodic signal in the frequency domain, and the period of the periodic signal in the frequency domain is used to represent the pitch frequency of the periodic signal; based on the periodic signal and at least one first A short-time spectrum signal, at least one second short-time spectrum signal is obtained, and the pitch frequency of each second short-time spectrum signal is the same as the pitch frequency of the periodic signal; based on at least one second short-time spectrum signal, a second audio signal is obtained , the pitch frequency of the second audio signal is the same as that of the periodic signal. The base tone frequency of the second audio signal obtained by the present invention is constant, and the pitch is very stable all the time, which produces the sound effect of "alien", and retains the sound characteristics in the first audio signal, with low distortion rate and no It is difficult or incomprehensible to understand during playback.

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 device 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 the audio signal processing method to transpose the recording to generate various sound effects. For example, the "Alien" sound effect. People can record on the terminal, and process the recording through the operation on the terminal, so as to create an abnormal sense of pronunciation, so that it sounds like 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 enhancing the harmonic components of the s...
