Audio signal post-processing method and device, storage medium and electronic equipment

Abstract

The invention discloses an audio signal post-processing method and device, a storage medium and electronic equipment. The method comprises the following steps: obtaining a first voice signal, framingthe first voice signal and converting the framed first voice signal into a plurality of frames of first frequency domain signals; performing confusion processing on first sub-frequency-domain signals,lower than or equal to a target frequency threshold value, in each frame of first frequency-domain signals in the multiple frames of first frequency-domain signals, reserving a second sub-frequency-domain signal higher than a target frequency threshold in each frame of first frequency-domain signal. According to the method and the device, the multiple frames of second frequency domain signals areobtained, then frame combination processing is performed on the obtained multiple frames of second frequency domain signals, the output second voice signals are obtained, and the purposes of protecting the voice signals, avoiding eavesdropping attacks and protecting privacy and safety of the voice signals are achieved by confusing the low-frequency-band parts of the output voice signals. According to the method and the device, the technical problems that terminal software and hardware need to be limited when voice signals are attacked and eavesdropped, the application range of a processing mode is relatively small and the user experience is poor in related technologies are solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to an audio signal post-processing method and device, a storage medium and electronic equipment. Background technique [0002] Cloud technology (Cloud technology) is a general term for network technology, information technology, integration technology, management platform technology, application technology, etc. based on cloud computing business model applications. It can form a resource pool, which can be used on demand and is flexible and convenient. Cloud computing technology will become an important support. The background services of technical network systems require a lot of computing and storage resources, such as video websites, picture websites and more portal websites. With the rapid development and application of the Internet industry, each item may have its own identification mark in the future, which needs to be transmitted to the background system for logical processi...
