How do I eliminate unwanted noise from audio file

Hi all, I am new to this forum and very new to Audacity. I have an audio recording that has a unwanted noise in it.

Can someone please give me instructions on how to remove the unwanted noise if it is possible?

Thank you,

Windows XP
Audacity 2.0.5
Downloaded the .exe installer

My guess is no. The Audacity Noise Removal Tool works by sampling a bit of the noise without the voices. That’s step one. Your interference is only there during vocals.

I’m finding even using the show painful way of notching out interference isn’t working because the noise doesn’t stay at one pitch.

Maybe someone else will have other ideas.

Do you know what happened?


Thanks for the reply kozikowski. I think the recording was made with an Ipaq PDA…remember those? :slight_smile: I have 2 songs this group sang back to back. The one song is perfect and the other came out with this annoying noise.

It’s not “straight” interference in the sense of hearing the lamp dimmer buzzing along in the show. This is a serious interruption of the actual audio data like the recorder can’t keep up.

It mostly goes away during silences. That’s what kills our tools. I would say you were outrunning the signal processing inside the recorder. You lucked out on the first one.
