Embodiment Construction
[0040] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0041] The main solution of the embodiment of the present invention is:
[0042] When the audio input signal is acquired, an envelope detection signal corresponding to the howling segment in the audio input signal is acquired;
[0043] When the detection value of the envelope detection signal is less than or equal to a first preset value and greater than or equal to a second preset value, frequency shift processing is performed on the howling segment, and the first preset value is greater than or equal to a second preset value. equal to the second preset value;
[0044] When the detection value of the envelope detection signal is greater than the first preset value, performing the frequency shift processing and negative feedback processing on the howling segment;
[0045] Outputting audio information according to th...
