I have an audio file, which sounds a little muffled due to compression (it's not very bad however). I want to clean it up as much as possible with Audacity or similar (free) software. I have a high quality sample of other parts of that audio, can that help me in any way? Just noise reduction isn't doing much work, I figured maybe some program or effect can help by comparing two samples and finding out the difference.
So essentially I have two audio files, one is complete but in lower quality, one incomplete but in high quality, I'm trying to merge them and have the best quality possible.
