I have a conversation record with an awful bzzzzz background noise coming from a GSM too near from the recording machine.
How do you thing I can reduce it, with way for filtering ? I’m a new user of Audacity.
In fact, I was not recording the gsm but a conversation meeting. At the beginning, the record is good. But after a while, the parasite gsm bzzzz background sound appears; i think someone moved its GSM from his pocket and put it in the table near the recorder, so that i have the wave parasiting sound (although the GSM is muted).
Here attached the spectrum, without then with the buzzy parasite sound
