Audacity Forum

Ah ok - good to know, thanks!

Thanks everyone for the help! Trebor's solution worked. A questions about Trebor's code. What does the "q" represent (with a smaller number for q being a wider notch).

Yeah, I did the same, though there are about three frequencies that stand out in the first half of the clip that only contains room tone. In the second half with speech those frequencies are subsumed and aren't as discernible amongst the speech.

The soundboard that a friend used produces steady background ringing at a certain frequency. I have used a nyquist prompt script in the past to eliminate a similar problem with different audio hardware (ringing at a different frequency), but don't know how to pinpoint the frequency of this ringing s...

You should be able to adjust the compressor to help that. Have you tried the "Compress Based On Peaks" setting? There's also "Limiter" and "Hard Limiter," but I'm not sure which ones come with Audacity. Some of those tools are home baked. If you want to commit to it, you can try Chris's Compressor....

Dynamic Audio Normalizer

This is fantastic, thanks so much!

Apply: High Pass Filter, Rolloff 24 dB, Cutoff Frequency 10 Hz (could probably use 20 Hz or even 40 Hz - higher values will remove more low-frequency noise) Notch Filter, Frequency 60, Q 10 Notch Filter, Frequency 120, Q 10 Now apply Noise Removal: Select a noise-only portion, then Effect > Noise R...

I have an interview recording where the levels were too low. I've tried using Compressor, Amplification, and Normalize to increase the levels of the recording, but the handful of peaks in the recording are hindering the more uniform amplification I could be getting from the compressor effect. You ca...

What would you recommend for removing this pesky ringing sound ... Notch filters at 1KHz intervals : paste Steve's code below into a thing called Nyquist prompt , then apply it like an effect to remove the whine noise ... (let* ((q 50) ; set the base Q for the filter (freq 1000) ; set base frequenc...

Hi. What would you recommend for removing this pesky ringing sound that my Blue Snowball microphone generated in this interview? I have experimented with Equalization and Noise Removal. With Equalization I am having trouble removing that specific sound without severely degrading the overall speech q...
