A low-pass filter reduces high frequencies above a chosen cutoff.
A low-pass filter lets lower frequencies pass while attenuating material above the cutoff frequency.
The slope controls how quickly the highs are reduced, so a gentle filter feels different from a steep one even at the same cutoff.
Low-pass filtering can remove hiss, soften harsh layers, tuck effects behind a lead, or keep low-priority parts away from the vocal range.
Used too aggressively, it can erase air, reduce transient clarity, and make a mix feel smaller than intended.
Move the cutoff while the full mix plays, then back off before the part loses its role. Solo checks can lead to filters that are too dark.
Meter Core helps confirm that filtering changed tone and space rather than simply lowering the part enough to hide it.
