Drop your song in the box, press Play and pick a preset like Heavy. Adjust Boost and Bass frequency until it hits right, then click Export MP3.
A built-in limiter catches the peaks and the volume is trimmed as you boost, so it stays loud without crackling. Extreme settings on already-loud songs can still sound heavy, so trust your ears.
It sets how low the boost reaches. Around 60 Hz is deep sub bass you feel, 80 to 100 Hz is punchy kick and bass, and higher sounds warmer and boomier.
+6 dB is a noticeable lift, +12 dB is heavy, and +20 dB is car-rattling earthquake mode.

Yes. Click Export MP3 for a small file, or Export WAV for full quality.

Boosting bass makes a song louder, which can make it crackle. This tool trims the volume as you boost and uses a limiter to catch peaks, so the result stays clean. For the best sound, boost around 60 to 90 Hz instead of cranking everything.
Want that bass boosted car sound? Try the Earthquake preset around 60 Hz. For headphones, Heavy at 80 Hz is punchy without being tiring.
Everything runs in your web browser, so it works on iPhone, Android, Windows, Mac and Chromebook. Save an MP3 and play it in any music app.
