How do you remove noise from a noisy signal in Python?

Noisereduce is a noise reduction algorithm in python that reduces noise in time-domain signals like speech, bioacoustics, and physiological signals. It relies on a method called "spectral gating" which is a form of Noise Gate.

Does a low pass filter remove noise?

A low pass filter (LPF) is used to remove high frequency noise from the signal and preserves the low frequency components in the signal. Whereas a high pass filter is used to remove low frequency noise and preserves the high pas components.
