The main disparity between LPF-low pass filter and high pass filter-HPF is the frequency range which they exceed. AnHPF (high pass filter)is one kind of circuit which permits the high frequency and blocks low frequency for flowing through it. In the same way, anLPF (low pass filter)is ...
这里很重要的概念是,低频过多的问题往往发生于「迭加」后 ; 个别乐器的声音听起来OK不代表不需要清理低频,即使低频不明显、它的的确确存在那里。而我们处理的方式是使用HPF(High-pass filter):HPF是一种特殊的EQ,如同它的名字:让高于特定频率(cutoff frequency)的讯号通过,换句话说,就是滤掉所有低于特定频率(cuto...
Low-pass filter: A‘low-pass filter’, also referred to as a ‘high-cut filter’, allows only frequencies that are lower than a certain point to pass through. Simultaneously, it filters out the frequencies that are higher than that point. ...
High-pass vs. low-pass filter While high-pass filters allow the high frequencies to “pass” through, low-pass filters allow the low frequencies to pass through. They are two sides of the same coin, but they serve different purposes. High-pass filters are often described as “sharpening” ...
