EQ High-Pass Filter and Low-Pass Filter 高通及低通濾波

Jacques

graphic equalizer 主要用途是處理MIC 的 Feedback 的問題，High-Pass / Low-Cut Filter and Low-Pass / High-Cut Filter 係方便唔使要CUT 太多頻率。也可以令MIC 收到的底噪較少。

用在room acoustics ，Low-Cut Filter  / High-Cut Filter 應該完全唔CUT，然後再每個 Band 處理。

理論上 room acoustics 用 parametric EQ 會比較好，但都要用Audio Analyzer 配合,
不過唔用DSP 去處理，Tune完根本就只不過係自已喜好！

Thanks!
"Low-Cut Filter  / High-Cut Filter 應該完全唔CUT，然後再每個 Band 處理。"...這個我看完User Manual亦有說:"LOW CUT...whereby the filter lets the signal pass through unprocessed, when the control is in 10Hz position. HIGH CUT...whereby the filter lets the signal pass through unprocessed, when the control is in 30kHz position."，我會試試看!
