What is a Gaussian high-pass filter?

The Gaussian high pass filter attenuates frequency components that are near to the image center (W/2, H/2); Figure 3, 4, 5 shows the result of Gaussian filter. Ringing (wave) effect is avoided in the Gaussian filter.

Should I enable high-pass filter?

If you are broadcasting or reinforcing sound outside, and even your best windscreen can't keep out the persistent low-frequency rumble from wind noise, then stopping it right at the source may be your best option. Highpass filters are excellent for this application.

What does a high-pass filter HPF do?

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.
