hopefully this is the right place to ask.
I'm working on a project, and I filmed myself playing the piano with my webcam. Now I don't need any grade A sound here, it's ok that's it's kinda grainy and low quality. But the problem is I accidentally set the computer's microphone sensitivity too high, and the sound is just terrible, there's a lot of noise even before I start playing, and the piano itself sounds extremely enhanced to the point that it doesn't sound like anything
Another problem is - I have a deadline. I don't know If I'll get to record another session before I have to finish the project. I have to know - is there's a way to improve the sound quality (I already extracted the sound), or would trying to do that be a waste of time?
Thanks in advance
p.s.
I'm running Ubuntu, so free software is better. But I have Windows on a VM as well, if I ever need it.
