I want to implement basic noise reduction. I'm recording audio using a microphone mounted on a drone. I would like to filter the audio file from drone noise. What's the best way to do it ?
My first idea is to first record sound that is emitted by a drone only and convert it using fourier transform to see which frequency has the most energy. Then I could do the same thing with audio file with drone noise.
My question is how to cancel this drone noise ?
Most of its power is in the low frequencies.
Edit. Community noise, including aircraft and motor vehicles, typically ranges between 50 Hz and 5,000 Hz. So basically if I filter noise from propellers I might also filter sound from vehicles?
