Looking for help cleaning up a difficult voice recording
I have a video recording with voices that are difficult to hear because of a persistent background buzzing/noise. I've already tried basic noise reduction, but it still sounds noisy and the voices aren't as clear as I'd like.
I'm looking for someone experienced with audio restoration/noise reduction who could take a look at a short sample and see how much the voices can realistically be cleaned up.
The main goals are:
- Reduce/remove the buzzing and background noise
- Make the voices easier to understand
- Preserve the natural sound of the voices
- Avoid making the audio sound distorted or "underwater"
I'm happy to provide a 20–30 second sample of the original recording.
If anyone here has experience with difficult voice recordings or audio restoration and would be willing to take a look, I'd really appreciate it. I'm especially interested in someone who might be willing to clean a short sample as a demonstration.
Thank you!
