What does high pass do in EQ?

A high-pass filter is an EQ curve that is used to remove low-frequency sounds from an audio signal. It is called a high-pass filter because it allows high-frequency signals to pass through, while attenuating (reducing the amplitude of) lower-frequency signals.

What does high pass and low pass do?

A high-pass filter (HPF) attenuates content below a cutoff frequency, allowing higher frequencies to pass through the filter. A low-pass filter (LPF) attenuates content above a cutoff frequency, allowing lower frequencies to pass through the filter.

What does low pass EQ do?

A low-pass filter (LPF) is a type of band setting you'd see on your EQ. It will be positioned all the way to the right on the frequency spectrum of your EQ. When you apply it, it appears as a cut that slopes down to the right. This cuts the frequencies above (to the right) of the low-pass filter.

Which is better HPF or LPF?

A HPF can really help clean up vocals or instrumentation that doesn't have a lower frequency. A LPF does the exact opposite. It allows lows frequencies to pass through and filters out high frequencies. This is a great tool for instruments like a bass guitar or a kick drum to clean give a clean low end to your mix!
