My friend received an audio clip from a family member he is concerned about, but the clip is very low quality. He asked me to help clean it up, but I only have a little experience with digital audio. I'm worried that there is not enough information on the clip to extract the vocals.
I've seen tutorials using audacity that allow me to reduce noise and extract vocals. Reducing noise helps a little bit, but if I remove too much noise then I start removing the vocals as well, and I get nasty artifacts in the mp3.
The original file was an
amr file, I converted it to mp3 to be able to work with it. Could I have caused issues converting from amr to mp3 that may be going against me?
If anyone has any tips on advanced vocal extraction from audio with a ton of white noise that would be great.
Alternatively if anyone is a true pro and has time to help out a friend I could potentially send you the clip. It might be a real simple job for someone with a lot of experience, but I don't want to share it publicly because it does seem to contain sensitive info.
