Remove Low-Frequency Rumble
Footsteps, traffic, HVAC and handling vibration dump energy below the voice as inaudible-but-destructive sub-bass rumble. A clean high-pass removes it and tightens the whole recording.
How it works
We apply a steep high-pass filter (default 80 Hz) that lets the voice through and rejects everything beneath it. Removing this sub-bass also frees up headroom so the rest of the audio sounds clearer and louder.

Frequently asked questions
No. Rumble is broadband sub-bass energy from vibration; hum is a precise electrical tone. Rumble removal is a high-pass; hum removal uses notches. Many recordings benefit from both.
At 80 Hz it sits below almost all speech, so voices keep their body. Deep male voices can use a lower cutoff if the default feels thin.
It removes the low-frequency body of thumps and handling noise; sharp transient clicks are better cleaned with the de-click tool.
An 80 Hz high-pass removes sub-bass, so kick drum and bass-guitar low end can thin out. Lower the cutoff or skip this on bass-heavy music.
Yes. The default corner is 80 Hz, but deep male voices or music can use a lower setting to keep wanted low-frequency body.
Indirectly. Clearing inaudible sub-bass frees up headroom, so after normalization the audible content can sit louder and cleaner.
No. It is a single high-pass filter that runs instantly, even on long recordings, with no special hardware.
