Cleaning up noise, static

Audacity Help Forum Windows

Subject says it all.

This isn’t music it’s discussion/talking, but there is a lot on noise, sounds like scratching, static…

Is there something that can clean up some of that ?

Thanks

You should get us a little closer. Post a 10 sec WAV clip of the show. Pick a segment with one or two voices and a space where they stop talking for second or so or take a breath.

This is the formal document on posting clips. The forum will stop you if you try to make the clip too long. You can’t post an entire podcast chapter.

That’s a phoner, isn’t it? The guest is on a phone. You unbalanced your phone line. You can’t do that. I have several cheap devices that claim to be able to let me connect my recorder to a phone line and they’re all terrible.

I got some help with Effect > Noise Reduction (attached). I drag-selected 2.4 to 2.8 seconds and used that as the profile. I used 12, 6, 6 as the reduction settings.

I found a specialized ear-microphone that lets me do a good job with a telephone. The illustration is an Olympus TP-7. The TP-8 doesn’t need that little black adapter just before the white Mic-In adapter. Chances are good you can plug a TP-8 straight into the Mic-In of a Windows machine.

You put that in your ear and the telephone handset goes on top.
