Removing Noise from Audio File (Noise Only in Voice)

I am hoping someone can assist me. I am on Windows 10 and using 2.0.6 of Audacity.

I am editing a “Voice Only” MP3. For some reason, the recording this week includes Buzzing/Static. The issue is that it’s ONLY present when the speaker is talking. This means I cannot isolate the Buzzing/Static during a Non-Speaking portion to build a Noise Profile and remove from the entire recording.

Is there a method with Audacity that can remove the Buzzing/Static/Hissing that is only present when the speaker talks? During the silent parts, there is no Buzzing/Static/Hissing. I’ve googled and cannot find a method with Audacity.

One more thing to note. The first few seconds of the recording, there is no Buzzing/Static/Hissing. I was hoping I could select that section to use to then delete the Static from the rest of the File, but I can’t determine how that would work.

Any help would be greatly appreciated.

That’s because there isn’t one.

The first few seconds of the recording, there is no Buzzing/Static/Hissing.

Which is upside down. The Profile step in Noise Reduction needs a significant segment of Pure Noise with no voice in order to work. If the noise is only there during voice, that’s the end.

That confirms someone recorded a noisy podcast and then tried to rescue it with a really bad noise removal. And then gave it to you. Have a happy day.

That’s the kind of thing the earlier Effect > Noise Removal did. That’s the one in Audacity 2.0.6.

We can’t take effects and filters out of a production. Once somebody puts them in, it’s permanent.

So. Get the producer to send you the raw, unprocessed, WAV sound file and try Noise Reduction in Audacity 2.1.2 here.

Drag-select a fifteen second, mono portion of the show, export it, and post it here. We may be able to give you some pointers as to the best way to go.

By posting a sample on the forum, I mean the raw, unprocessed sound file you get from the producer, not the damaged one.

Thank you for the reply. The file I have is a raw file. It was a .aif
I converted to MP3 for Audacity. The hiss was present in the raw file as well.

The Admin is going to check the equipment this week as this has never been a problem.

Still. If it walks like a duck and quacks like a duck…

Somebody shot a damaged performance and tried to cover it up. I’m sticking with that. You should get Production to submit a short test recording for acceptance. If somebody does that again, it will be two shows you can’t use.

There is one other way to get this effect. Rachel Maddow has a very poor television studio (I’ve accused them of shooting the show on the NBC loading dock) and they use a noise gate on her voice. All her words are noisy and have tails on them followed by velvety silence.

You didn’t complain about tails.
