How to bass boost a song

  1. Drop a song.
  2. Set how much bass to add (6–10 dB is punchy; 15+ dB is the extreme "bass boosted" meme sound) and up to which frequency.
  3. Optionally adjust treble, preview, then download WAV or MP3.

How the bass boost works

A low-shelf filter raises every frequency below the cut-off by the chosen amount, with a smooth transition above it. A cut-off around 80–120 Hz targets kick drums and bass lines; going up to 200–250 Hz adds warmth but can make vocals muddy. Because boosting bass increases the overall level, the tool reduces the input level slightly and runs a limiter at the end, so the result does not clip into distortion.

Heavily boosted bass sounds best on headphones, car stereos and speakers with real low-frequency response; small laptop and phone speakers cannot reproduce much below 150 Hz. Everything is processed locally in your browser.

FAQ

What frequency should I boost?

60–120 Hz for punch; 120–250 Hz for warmth.

Why does it sound distorted?

Very large boosts can still overload your speakers. Lower the bass setting.

Can I reduce bass?

This tool only boosts. Lower the treble to emphasise bass instead.
