Six decibels is roughly twice as loud
Phone recordings from the back of a lecture hall, interviews with a shy speaker, old files mastered too quietly: a clean gain boost fixes most of them. +6 dB roughly doubles perceived loudness; +12 dB quadruples it. Push too far and peaks clip, so start at +6 and re-run in seconds if you need more.
Frequently asked questions
Will boosting distort my audio?
Only if the loud parts run out of headroom (clipping). Start with +6 dB; if the source was very quiet, +12 dB is usually still clean.
Can I make audio quieter too?
Yes, the −6 and −12 dB options attenuate. Handy for taming a recording that slams.
Is my audio uploaded?
No. The gain is applied in your browser via WebAssembly FFmpeg.
Is there a limit on files or length?
No. Your own device does the work, so there are no queues, caps or accounts.
