Laptop speakers, cheap earbuds and quiet mixes all leave the same complaint: not enough low end. This tool lifts everything below about 90 Hz — kick drums, bass lines, the weight of a voice — while leaving the rest of the track alone. The default is a gentle 3 dB lift you will feel more than notice; drag the shelf higher while the track plays until the low end sits right, up to a heavy +18 dB for earbuds that need real help. Boosting bass is exactly how tracks start clipping, so a limiter watches the output and holds every peak in check. The whole job runs on your computer, and the boosted file comes back as WAV or, if you prefer, MP3, M4A, FLAC or OGG.
Questions
Why does boosted bass usually distort, and why doesn't it here?
Low frequencies carry most of a track's energy, so lifting them pushes the loudest moments past full scale. Here a limiter rides the output and stops each peak just under 0 dB, which keeps the punch and drops the crackle.
How much boost should I use?
Start at the default +3 dB and drag the shelf while listening — the preview plays your changes live. Around +6 the lift is obvious; past +9 expect the whole track to sound noticeably heavier, not just the drums.
Does it work on voice recordings?
Yes — the default +3 dB adds chest and warmth to a thin voice memo without booming. More than about +6 makes speech muddy.
What format should I save?
WAV keeps everything and is the default. MP3 at 320 kbps is fine for listening and far smaller.
