Abstract

The invention discloses a squeal detection method, a squeal detection device, a storage medium and an electronic device, wherein the method comprises the steps of: obtaining the frequency-point standard deviation array of an audio signal to be detected, wherein the frequency-point standard deviation array includes the first frequency-point identifier of a frequency point, the power spectrum standard deviation of which satisfies a first predetermined condition in the audio signal; searching a target frequency-point identifier matched with the first frequency-point identifier in the peak array of the audio signal, wherein the peak array includes the second frequency-point identifier of a frequency point, the peak value of which satisfies a second predetermined condition in the audio signal;and the second frequency-point identifier includes the target frequency-point identifier; and, when the target frequency-point identifier is searched, taking the target frequency point corresponding to the target frequency-point identifier as the squeal frequency point in the detected audio signal. By means of the squeal detection method, the squeal detection device, the storage medium and the electronic device disclosed by the invention, the technical problem that the detection accuracy is relatively low in the existing squeal detection manner can be solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a howling detection method and device, a storage medium and an electronic device. Background technique [0002] In a sound reinforcement system, when a microphone is used to pick up sound, since the sound pickup area of ​​the microphone cannot be completely isolated from the playback area of ​​the speaker, the sound from the speaker is transmitted to the microphone through the space, and then amplified by the amplifier circuit, which will cause Acoustic feedback phenomenon. Among them, the acoustic feedback phenomenon will make the sound distorted. When the acoustic feedback is serious, it will whistle together. When the sound reinforcement system emits a howling sound, it will not only make speech and singing impossible, but also damage the human ear; in addition, Severe howling may also burn out the amplifier in the system or the tweeter in the speaker. Therefore, how to accu...
