Mix moves
Filter fade
A filter fade uses the mixer’s filter rather than the fader to move between records: the outgoing track is high-passed until only its top remains, while the incoming one opens up from below.
In practice
Filter rather than fade and nothing gets quieter — the outgoing track just stops taking up the bottom.
Sweep the outgoing channel’s high-pass up over eight or sixteen bars while the incoming track comes in unfiltered, then cut the outgoing channel when there is nothing left worth hearing. Do it slowly enough that the sweep reads as movement rather than as an effect. Two filters moving at once — one opening, one closing — is a stronger version but harder to keep balanced, and one filter plus a straight fader move gets most of the way there with half the risk.

What it hides
Where these come from: Standard filter-transition practice on club mixers — technique, not catalog figures. For what we can measure, see the control itself.
Why it matters
It works because it moves the two tracks out of each other’s way in frequency rather than in level. Nothing gets quieter — the outgoing record simply stops occupying the bottom, which leaves room for the incoming one without either track disappearing.
It is also the most forgiving transition on records that do not want to blend. A high-pass hides a bassline that disagrees, a vocal that clashes and a groove that is not quite locked, which makes it the move to reach for when the pairing is imperfect but the moment is right.
Frequently asked
Is a filter fade easier than a bass swap?+
More forgiving, yes. A high-pass hides a clashing bassline rather than requiring the two to agree, which makes it the safer move on an imperfect pairing.
How long should the filter sweep take?+
Eight to sixteen bars. Fast enough and it reads as an effect rather than a transition, which is a different and much more obvious thing.
Should I filter both tracks at once?+
It is a stronger version and harder to balance. One filter plus a fader move achieves most of it with considerably less that can go wrong.
Related terms
Filter
A filter removes everything above or below a moving cutoff point. A high-pass strips the bottom away as you turn it up; a low-pass takes the top off as you turn it down.
Blend
A blend is a transition where both records play together for a stretch — long enough that the overlap is part of the music rather than a join between two pieces of it.
Bass swap
A bass swap hands the low end from one track to the other in a single move: the incoming bass comes up at the exact moment the outgoing bass goes down, so only one record is ever carrying the bottom.
Fade out
A fade out lowers a track’s level to nothing over several bars. As a transition it is the simplest move available; as an ending it is the one that tells a room the night is over.
