When on, changing a setting replays from the green ⟳ marker on the waveform (drag it anywhere — it defaults to the start). When off, changes apply live while the song keeps playing.
How do I boost the bass in a song online for free?
Drop your audio onto SnipSound's Bass Booster, choose a boost level (Deep is +8 dB at ~110 Hz), preview, and download. A low-shelf filter lifts the low end and a soft limiter keeps it from clipping — all in your browser, nothing uploaded.

Why a limiter matters
Most online bass boosters just crank a low-shelf filter, which pushes the loudest moments past 0 dB and adds harsh clipping. SnipSound puts a soft limiter after the boost, so the low end gets louder and fuller while the peaks stay controlled — the difference between "boosted" and "broken".
