Very Light Bass Boost Preset
A +3 dB nudge for tracks that just need a touch more.
What is this tool
AudioToolKit applies a very light bass boost online for free, in your browser. A +3 dB low-shelf lift from 120 Hz down adds body to thin mixes without pushing the level toward clipping. The boosted track downloads as MP3 or WAV, and the file never leaves your device — a subtle first step before the stronger Light, Moderate, Heavy and Extreme presets.
