What is a bass booster?
A bass booster is a low-shelf equalizer that amplifies frequencies below a chosen cutoff (typically 60-250 Hz), making kick drums, bass lines and sub harmonics feel fuller and more impactful. RemoveVocals Bass Booster runs in your browser with 5 presets from Light to Sub Bass, real-time preview, and automatic clipping prevention. Free, private, unlimited.

How much bass boost is too much?
Above +12 dB you'll start to hear distortion and clipping on most mixes. For listening pleasure, +3 to +6 dB is ideal. +12 dB (Heavy) works for bass-light recordings. +18 dB (Extreme) is for creative effects and car audio demos, not mastering.
What is sub bass?
Sub bass refers to frequencies below 60 Hz — these are felt more than heard and require a subwoofer or a pair of large-driver headphones to reproduce. Our Sub Bass preset boosts +15 dB centered at 60 Hz, great for hip-hop, EDM and trap.
Does bass boosting damage the audio quality?
Moderate boost (0-6 dB) is effectively transparent. Heavy boost can introduce clipping if the source already has strong bass. Our tool applies automatic makeup gain and soft-limiting to avoid digital distortion.
Can I boost only the sub without touching the mids?
Yes. Lower the cutoff frequency to 60 Hz and you'll only affect sub bass. Raise it toward 250 Hz to include more of the low mids (kick body, bass guitar fundamentals).
Does it work on Bluetooth headphones?
Yes. The boost is baked into the downloaded WAV, so it plays back through any speakers or headphones — wired or Bluetooth. For best results, use headphones with strong low-end extension (Sony, Sennheiser, Beats, etc.).
