About the Bass Booster Online
Completely free: free account, no credits, no limit. It runs in your browser, so your audio stays on your device.
The Bass Booster lifts everything below about 110 Hz with a low-shelf EQ, from a gentle +2 dB to a heavy +18 dB. The rest of the song is lowered slightly and a limiter catches the peaks, so the result is bassier without distorting.
Use it for car speakers, small phone speakers or the bass-boosted edit style. Everything runs on your device.
What you can use it for
- ✓Bass-boosted edits
- ✓More low end for small speakers
- ✓Fuller-sounding demos

Frequently asked questions
How much bass boost should I use?
+
+4 to +8 dB sounds fuller without being obvious. +12 dB and above is the heavy bass-boosted style.
Will it distort?
+
A limiter stops clipping, but very high settings on already loud songs can sound squashed. Lower the boost if it pumps.
What do I get?
+
An MP3 (192 kbps) or a WAV file, whichever you choose, ready to download straight away.
Is it really free?
+
Yes. It is completely free, with a free account: no limit and no watermark. It runs in your browser, so your audio stays on your device.
