After trying several tutorials and solutions to help my brother with the attached audio, I am still unable to figure out what the affected frequency is nor the best solution to go around this.
I have tried working directly in the affected areas in the Spectogram after exploring the audio with the Plot Spectrum but I haven’t succededed.
If someone has the time to listen to it, the sound is this loud popping mic or electric noise in the first half of the audio: it repeats 21 times in the first minute of his recording and then disappears. Sometimes is louder and sometimes lower…
It was basically filmed in his celphone. He is a viual artist and is sudmitting a video explanation of a piece to a curatorial team. The quality is not good but it will be enough if I’m able to recognize and solve the error.
Paul-L’s declicker plugin on default takes the worst off it.
It sounds like handling-noise.
(it’s not one-take, it could be them repeatedly handling the device to pause it at the end of takes).
As others have said, it sounds like something is tapping against the mic / phone.
I’m impressed with how well Trebor removed the noises. I’m surprised that it worked so well, but I’m guessing that it required fiddling around with the settings to get such a good result (Paul’s declicker effect is not very user friendly).
The recording has lots of discontinuities.
Just did a quick sample “re-draw”, actually goes pretty quickly.
The first second or so could do with a bit more work.
WOW! I am super impressed with the results! I was almost convinced that this specific noise was not probably going away!
I will download the plugins and fiddle around with them.
THANKS A LOT!
After talking to my brother, I guess the noise was actually produced by some kind of electronic interference.
I gave him a lot of shit because his art installation is amazangly complicated and sophisticated in terms of visual arts - he not only conceived and built everything in the instalation from scracth but also built all the electronic circuits to produce the interactions- but he could not produced a decent audio GRRR
I attached some pics for those who asked about the installation.
Just updating to avoid confussion in case this solution could be useful to someone else:
My brother did some tests in a different room without even touching the celphone and yes, it seems to be a mechanical problem in the mic of the cel itself as suggested.
