Практическое применение

ФВЧ вырезает низкие частоты. Очевидный эффект в том, что если ваш звук слишком басовый или грязный, вы можете уменьшить низкие частоты с помощью ФВЧ.

A not-so-obvious corollary is that the HPF effectively emphasizes the higher frequencies — “cutting low frequencies” isn’t really different from “boosting high frequencies”. So if you want to make very buzzy or bright sounds, bringing in a little (or a lot) of HPF will get you there.

Try monkeying around with the HPF on the basic patch, or any other patch you can find. Its effect is pretty easy to understand, and since there’s only one parameter that can be adjusted, it is easy to explore.

Note that many of the same things you tried for the LPF can be applied to the HPF. Try doing a HPF filter sweep. Load the Basic Patch.

• ENV 3 Attack = 78

• ENV 3 Decay = 98

• ENV 3 Amount = 99

• ENV 3 Destination = HPF (Highpass Frequency/HiP)

• Highpass = o 5 (so it can be modulated)

Play a few notes.

Try setting up an LFO to modulate the HPF parameter. Experiment with different waves, frequencies, and amounts — a little modulation of the HPF (slow rate, shallow depth) can make a dull sound a little more interesting.

Or try using ENV 3 to modulate the HPF— this can provide some interesting sonic contours to a sound.
