Bass boost amplifies the low-frequency range of your audio (roughly 60-250 Hz) using a low-shelf equalizer filter. Unlike a plain volume increase, a bass boost targets only the low end, so vocals and highs stay untouched while kicks and basslines gain weight.
This tool gives you a bass level slider (0 to +24 dB) plus one-click presets for common use cases: Mild for a subtle lift, Punchy for modern pop energy, and Deep for sub-heavy electronic music.
80-120 Hz for deep sub-bass, 150-250 Hz for warmth and punch in vocals and guitars.
Moderate boosts (up to +12 dB) stay clean. Extreme boosts can clip loud passages, so listen back at full volume.

Yes, it supports MP3, WAV, OGG, AAC, and any other format your browser can decode.
