How this bass booster works
The tool applies a low-shelf filter centered at your chosen cutoff frequency, boosting everything below that point by the gain you set. This is the same approach used by audio mastering plugins like FabFilter Pro-Q, iZotope Ozone, and Logic Pro's EQ.
The limiter sits after the EQ to catch any clipping introduced by heavy bass boost. Without it, +12 dB on the low end can easily exceed 0 dBFS and produce nasty distortion.
Recommended settings
- Hip-hop / EDM: +6 to +9 dB at 80–100 Hz (sub-bass focus)
- Rock / metal: +4 to +6 dB at 120–150 Hz (kick & bass guitar)
- Podcast / voice: +2 to +3 dB at 200–250 Hz (warm up thin voice)
- Headphone listening: +6 dB at 80 Hz to compensate for small driver roll-off
FAQ
Will heavy bass boost damage my speakers?
Standard speakers handle +6 to +9 dB fine. Above +12 dB on small phone or laptop speakers, low frequencies start to overshoot driver excursion limits — keep limiter on and you'll be fine.
What cutoff frequency should I use?
80 Hz for serious sub-bass on music. 120 Hz for general "warmth". 200+ Hz for podcasts and voice. The lower the cutoff, the more selective the boost.
