Engines and licensesAbout Bass Boost
Bass Boost lifts the low end of the spectrum, where the kick drum, bass and 808s live. The preset applies +8 dB, a clear boost that rarely clips, and in custom mode you choose any value from 0 to +15 dB and the frequency it works up to, from 40 to 250 Hz. Only the lows change: mids and highs stay as they were.
What you can do with it
- 01
Music for the car
Road noise eats the bass. An 8 to 12 dB boost makes up for it if your system has a subwoofer.
- 02
Workout playlists
More physical bass gives the session energy. With over-ear headphones, 8 to 10 dB usually works well.
- 03
Videos with impact
Sports edits, gaming highlights or car videos hit harder with a more present bass.
- 04
Thin recordings
Acoustic tracks, folk or older recordings have room in the lows and benefit from a moderate boost.
How it works, in 3 steps
Upload the song
MP3, WAV, FLAC, AAC and OGG are supported. Any genre works, though the effect is most obvious in hip-hop, electronic or trap.
Choose the boost
Keep the +8 dB preset or switch to Custom: pick the boost, from 0 to +15 dB, and the frequency, from 40 to 250 Hz.
Listen and download
Pay attention to the kicks: if they crackle, drop 2 or 3 dB. When it sounds clean, download it as MP3, WAV, FLAC or OGG.
Where it works and how much to boost
Sub-bass (20–60 Hz)
Felt in the chest more than heard. It needs a subwoofer to reproduce well.
Bass (60–100 Hz)
The thump of the kick and the body of the bass. The range that gives punch.
Low mids (100–250 Hz)
Warmth and weight in the mix. Too much and the sound gets boomy.
+3 to +5 dB
A subtle boost, for small speakers or music that already has little bass.
+6 to +8 dB
The recommended range for almost everything: clearly noticeable with a low risk of clipping.
+9 to +15 dB
Very prominent to extreme bass. It needs good speakers or a subwoofer, and a listen before downloading.
Tips for better results
- Start at +6 or +8 dB and go up 2 at a time. When you hear distortion, step back once: that's your maximum for that song.
- If the track is already bass-heavy, like trap or dubstep, stay between +4 and +6 dB.
- For phone or laptop speakers, don't go past +6 dB: they can't move that much air and they rattle.
- Check it on a phone speaker before sharing: if it sounds good there, it'll sound good almost anywhere.
- Don't combine maximum boost with maximum volume: it's the fastest recipe for clipping.
Frequently asked questions
Which frequencies does it boost?
The lows below the frequency you choose: 100 Hz by default, adjustable from 40 Hz (sub-bass only) to 250 Hz (full-bodied bass). That's where the kick, bass and 808s are; mids and highs are untouched.
How many dB should I add?
For almost everything, +6 to +8 dB. In the car or at the gym, +8 to +10 dB holds up; on small speakers, +4 to +6 dB is better; and +12 dB or more only on systems built for bass.
Will it distort my song?
With moderate boosts, rarely. The risk shows up at +12 to +15 dB on tracks that already have lots of bass. If you hear crackling, blurry lows or buried vocals, drop 2 or 3 dB.
How is it different from Volume Booster?
Bass Boost raises only the lows and changes the tonal balance. Volume Booster raises everything equally and the tone stays the same. For louder audio with more bass, you can use both, gently.
Is it safe for my speakers?
At reasonable volumes, yes. An extreme boost at full volume can strain small speakers without a subwoofer. If they vibrate or buzz, lower the boost or the volume.
