Speaker howling during a video call, livestream, karaoke session, or online class? ๐Ÿ”Š๐Ÿ˜ตโ€๐Ÿ’ซ

What causes it? When sound from the speaker is picked up by the microphone, it creates an acoustic feedback loop, resulting in that familiar high-pitched squeal.

1๏ธโƒฃ FFT Spectrum Analysis
Detects abnormal howling signals

2๏ธโƒฃ Automatic Frequency Detection
Identifies howling frequencies that exceed the threshold

3๏ธโƒฃ Dynamic Notch Filtering
Precisely suppresses detected frequencies

4๏ธโƒฃ Gain Control
Helps prevent new howling peaks
