Hi all,
I’m working with some voice recordings where there’s a noticeable low-frequency hum in the background, but most online tutorials for noise removal also end up dulling the voice quality if I apply them aggressively. I’m hoping to isolate and reduce just the hum without losing clarity in the spoken parts.
Here’s my setup:
Audacity 3.2.5 on Windows 10
Source recordings captured on a USB mic
Things I’ve tried so far:
• Using Noise Reduction with a noise profile taken from a silent section reduces the hum a bit, but also affects voice clarity.
• Applying High Pass Filter at various cutoffs too low doesn’t fix it, too high thins the voice.
• Using Notch Filter for known hum frequency helpful but not enough on its own.
For context, I manage audio for projects like [link deleted] where spoken instructions and narration need to sound clear even after cleanup, so getting a solid balance is important.
Is there a workflow or combination of effects in Audacity that’s proven effective for reducing low-frequency hum while preserving vocal fidelity? Are there specific filter settings or processing order that others here have found that works well?
Thanks for any tips!
