Utilizing a low-pass filter and polarity reverse

“

Our discussion of delay parameters so far has covered level, delay time, and feedback. A lot of effects can be built with just these parameters alone, but more cool features await. Another common parameter in delay devices might be a bit surprising at first, a low-pass filter. Low-pass filters attenuate high frequencies but allow the low frequencies to pass on through. Utilizing the low-pass filter to reduce the high frequencies in your delayed signal can be effective way to create the illusion of distance for elements in your mix. It can help to push your track back deep into the mix away from the listener. In addition, attenuating the presence range of the delayed signal, the mid-frequencies, can help prevent some delay effects from cluttering the mix and distracting your listener. In this way, the low-pass filter helps us fit more pieces into the mix without things getting too crowded. A potentially distracting delay effect can settle neatly into a full mix with just a little bit…
