I have a wma file that has a conversation on it from my long deceased grandfather when he was being interviewed for a book. The recording as far as I know, was just made with a standard cassette device back in '84.
About 1/2 way in the lady making the recording turned the mic off for a sec, and when she turned it back on either she forgot to put the input volume up or the mic had something covering it, as you can still hear the conversation but it is severely muffled with foreground noise.
This is the only recording we have of my grandfathers voice, and I would dearly like to clean the muffled part of it up so it was more audible. Would it be possible to use Audacity to do this, and if so, what is the best way?
I’ve attached a 40 second sample of it, I converted the wma to flac with VLC, then opened it with audacity and exported a snippet that covers from when it went from clear to very muffled.
I got nothing. The voices are too far in the mud to use Noise Reduction. You can try Effect > Equalization: Telephone Filter, but that also makes the voices sound like a telephone and may not help clarity.
