Problems solved by technology
The howling phenomenon of audio equipment has a great impact on the sound quality of the equipment audio. Howling will cause a sharp drop in sound quality and affect user experience. Since howling is generated by the positive feedback of the system, the system load will gradually increase, even will damage the device

This application is applicable to the field of computer technology, and proposes an audio signal processing method, including: performing frame division processing on the detected audio signal to obtain multi-frame signals; performing windowing processing on each frame signal respectively, and performing Fourier leaf transform to obtain the frequency spectrum of each frame signal; use the preset frequency point clustering algorithm to analyze the frequency spectrum of each frame signal respectively, and detect the howling frame signal; use the preset howling frequency point judgment criterion from the A howling frequency point is detected in the howling frame signal; performing notch processing on the howling frequency point, and outputting a frame signal after the notch processing. Since the frequency spectrum of each frame signal is analyzed by using the preset frequency point clustering algorithm, after the howling frame signal is detected from the frequency spectrum of each frame signal, the howling frequency point is continuously detected, and the howling frequency point is notched. , and output the frame signal after the notch processing, which can effectively suppress the howling phenomenon of the audio device, improve the sound quality of the audio device, and improve the experience effect of the user.
Description
Technical field [0001] The present application belongs to the technical field of computer, and more particularly to a method, apparatus, a computing device, and a storage medium for audio signal processing. Background technique [0002] With the development of communication technology, with the development of communication technology, wireless communication equipment greatly facilitates people's daily lives and work, especially mobile terminal equipment, not only in personal life, but also in various industries to wireless communication equipment. Demand is also more widespread, such as rail transit, security, public security and other industries have a more special demand for special wireless communication equipment. [0003] Due to the special use scenario of the private network industry, the volume requirements of the audio terminal device are relatively large, which exists between the audio devices. The phenomenon is a kind of sound feedback. When the two equipment calls, the...
