I’m trying to digitize these tapes I found at a tag sale by a nun who gave lectures through the ‘90s and early ‘00s on relationship. At around the 24 second mark, there’s this persistent noise interference, which to me sounds a lot like helicopter blades whirling. I don’t think it’s a real thing that was picked up during the original recording, as it remains consistent in level and pitch throughout. I’ve various tricks I’ve seen recommended by other forums, but no luck. In fact, I haven’t been able to find someone who has matched my experience yet.
I’m very new to the whole audio editing field, and I find it both fascinating and a little overwhelming, so it is entirely possible I’ve just simply missed some obvious solution that’s staring me right in the face. Any help you can provide will be much appreciate.
You can try Noise Reduction which requires you to feed it a “fingerprint” of noise-only.
But if the noise is bad you can get artifacts/side effects and sometimes “the cure can be worse than the disease.”
You might find better AI noise reduction online. AI is getting really good and I saw a video showing some really good results with spoken voice. (Music might be trickier.)
…Pros still record in soundproof studios with good equipment because there is only so much you can do, even with pro software.
I’ll definitely take a look at that, I usually avoid AI stuff, but it’s worth a check-out, thanks!
Unfortunately, this Sister seemed to record under naturally non-ideal circumstances, namely a lecture hall in Suffolk County, Long Island, live. Alas! So it goes.
