How to boost the bass of a song
- Drop your song into the box or choose it. It starts with a normal bass boost: +6 dB at 60 Hz and +4 dB at 150 Hz.
- For more, pick Strong bass boost in Preset, or raise the 60 Hz and 150 Hz sliders yourself, up to +12 dB.
- Play the result next to the original and download it when it sounds right.
What a bass boost does
Bass is the low end of the sound: the kick drum, the bass guitar or synth, and the weight of voices. A bass booster raises those frequencies and leaves the rest alone. This one uses the same filters as the audio equalizer, set up for bass: the 60 Hz band adds sub bass you feel more than hear, and the 150 Hz band adds the punch you can hear on most speakers.
Because the boost can push peaks over full scale, the result is checked after the boost. If anything would clip, the whole song is turned down by just enough, so you get more bass without distortion.
Tips for a cleaner boost
- Start with the normal boost: many songs are already mixed with plenty of low end, and more can sound boomy.
- Watch for muddiness: if the result sounds thick or unclear, lower the 400 Hz band by 2 or 3 dB.
- Check on the speakers you will use: headphones show off sub bass that phone speakers can’t play.
- Louder afterwards: run the result through volume booster or normalize audio if it needs more level.
