I was managing an interview in Germany. After leaving the country, one of my guests didn’t like how the intro sounds like, so he recorded that part again and asked me if I can replace the original one.
The original recording that he wants me to delete is here Target Quality
The background noise (if needed is here Target Background Noise
The low-quality file he recorded and sent over the internet here Raw Source
What can I do to make the “Raw Source” file sound in quality of the “Target Quality” file on audacity? It sounds like a phone call recording and a bit muted.
