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(cutoff frequency)的讯号。 HPF的控制主要就是要决定Cutoff frequency的高低,而我们的目标是:清掉除了Bass、Kick以外听起来不明显但无用的低频。挂上HP...

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” ...
