IPA: /ˈloʊpæs/
KK: /loʊpæs/
A type of audio filter that allows low frequencies to pass through while blocking higher frequencies.
The sound engineer used a lowpass filter to enhance the bass in the music track.
Lowpass → It is formed from "low" (from Old English "lōw", meaning not high) and "pass" (from Latin "passare", meaning to go or to allow). The term "lowpass" refers to allowing signals or frequencies that are low to pass through while blocking higher frequencies.
Think of something that allows only the 'low' frequencies to 'pass' through, which is what a lowpass filter does.
