I have an mp4 file that was recorded from a skype presentation. It is full of audio feedback of the presenters own distorted voice. Unfortunately, he talks over his own distorted feedback so they occur at the same time and I can't separate them.
I am very new to audio editing but not to software or analysing waveforms as I am an electrical engineer
What I have tried
1) Visual repair using various frequency selections, freehand, etc...
2) Noise Reduction using selected range containing only feedback.
I have not had much success, but it is possible that I am not operating it correctly though I have followed the cyberlink help topics
Any suggestions are welcome.
thank you!
