low-pass filter

Bass frequencies only

A low-pass filter is a circuit or algorithm that allows signals below a certain frequency to pass through while attenuating higher frequencies.

In audio, it cuts treble to leave bass; in image processing, it blurs by removing fine detail.

The cutoff frequency determines where attenuation begins.

Apply a low-pass filter to remove the high-pitched noise.
