Filtering noise from an audio file - MathWorks
https://www.mathworks.com/matlabcentral/answers/400244-filtering-noise-from-an-audio-file
I have a corrupted audio file which contains a message with very loud noise, and I should filter the noise as much as possible. I tried couple of filters, and I could eliminate some of the noises but it's not enough. P.S. The expected audio file is also there, which I plotted it to compare the filtered one with it.

Signal Processing: Filtering Out The Noise
https://www.catchpoint.com/blog/signal-vs-noise
Depending on the requirement, either linear filters (such as SMA) or non-linear filters (such as median filter) can be used. Some common filters used are Kalman filter, Recursive Least Square (RLS), Least Mean Square Error (LMS), Wiener-Kolmogorov Filters. Noise reduction can be achieved in both the time domain as well as frequency domain.

Hearing aids with this digital processing strategy provide advanced comfort in background noise, making understanding speech in background noise easier than it has been previously. Because digital signal processing looks at the psychoacoustic principles of the signal and differentiates between noise or speech, the aid can shift its focus and the volume will …

The PWM should be filtered-out before sending the audio to an amplifier. (You should filter-out the DC too.) Ideally, the PWM should be well-above the audible range so you can't hear it. If the PWM is less than 20kHz, you may hear it if it's not filtered-out. (You will hear the default ~500Hz PWM, but I'm sure you're not using that!) But for high-quality audio, you don't …
