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.
Yadda yake aiki
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.
What it's good for
- Desk and floor vibration
- Traffic and HVAC rumble
- Handheld mic handling noise
- Podcast desk thumps

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.

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.
