扩声系统中只要使用话筒,话筒啸叫就会时不时地出现,各个频段的啸叫直接影响了语言清晰度和传声增益的提高,甚者会造成功放及扬声器等设备的损坏。反馈抑制器是除使用图示(参数)均衡器、移频器等工具以外又一种抑制话筒啸叫的工具。Phonic i7100是48kHz,32bit的2声道的高性能数 As long as the microphone system is used, the microphone whistling will appear from time to time. The whistling of each frequency band directly affects the speech intelligibility and the gain of the sound transmission. In some cases, the amplifier and the speaker may be damaged. The feedback suppressor is another tool for suppressing the howling of the microphone in addition to using the illustrated (parametric) equalizer, frequency shifter and other tools. Phonic i7100 is 48kHz, 32bit 2-channel high-performance number
