lowpass
Cuts high frequencies
Lowpass describes a filter that allows frequencies below a certain threshold to pass through while blocking higher frequencies.
In audio processing, a lowpass filter removes treble and hiss: Apply a lowpass to soften the harsh highs.
In electronics and signal processing, lowpass filtering smooths data by eliminating rapid fluctuations.
Often hyphenated as low-pass.
