???? How do you do it? And in what applications is it most useful?

Thank you.
 
Highpass is exactly as it sounds. Anything above a preset "Cutoff" frequency will be allowed to continue thru the filter, anything below it will not. It is most commonly used to eliminate any low-end frequencies, and thin out a sound. It's very popular for sizzling lead keyboard sounds. A lot of people use them on vocals to remove rumble or other unwanted low-end material.
Most popular parametric/paragraphic EQs allow to determine how a specific band will act (i.e HPF, LPF, Notch, Shelving etc.). How you would set one up would be dependent on your setup. Are you doing this in hardware or software? What plugins might you be using. There are some good freebie filter plugins out there like Little Duck, and there are plenty of high-end plugins available. But chances are you probably already have what you need. More info would help.
 
If it makes it any easier for you, think of a high pass filter in the opposite way.

A high pass filter is a low frequency blocker of some set frequency.

I don’t know if that’s helpful or not? Probably confused you more?

A highpass filter can also be called a lowcut filter

A lowpass filter can also be called highcut filter

A common use of them both would be to control the frequency range of a reverb's output, I usually use a lowpass at 3.6k and a highpass at 200 hz on the output of a reverb plugin when it's on an aux return channel and set 100% wet, this restricts the reverb's output to be between 200 hz and 3.6 khz, removing lowend boominess, and taking a good bit of the high end brightness out, leaving a darker/warmer reverb sound.
 
Hhhhmmm....maybe it's the khz and hz I'm not understanding...I'm not sure where to cut...
