Howling suppression method and device, computer equipment and storage medium

Abstract

The invention relates to a howling suppression method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a current audio signal corresponding to a current time period, and performing frequency domain transformation on the current audio signal to obtain a frequency domain audio signal; dividing the frequency domain audio signal to obtain sub-bands, and determining a target sub-band from the sub-bands; obtaining a current howling detection result and a current voice detection result corresponding to the current audio signal, and determining a sub-band gain coefficient corresponding to the current audio signal based on the current howling detection result and the current voice detection result; obtaining a historical sub-band gain corresponding to the audio signal in the historical time period, and calculating a current sub-band gain corresponding to the current audio signal based on the sub-band gain coefficient and the historical sub-band gain; and performing howling suppression on the target sub-band based on the current sub-band gain to obtain a first target audio signal corresponding to the current time period. By adopting the method, the howling suppression accuracy is improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a howling suppression method, apparatus, computer device and storage medium. Background technique [0002] With the development of Internet communication technology, voice calls can be made based on the network, for example, voice calls of various instant messaging applications. However, during a voice call, especially during a voice conference, two or more voice call devices are often located in close distances. For example, in the same room, howling is very likely to occur at this time, thereby affecting the voice call. the quality of. At present, howling is usually avoided by adjusting the distance between the voice communication devices. However, when the distance adjustment cannot be performed, howling will be generated, thereby reducing the quality of the voice communication. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide a ...
