What is the audio volume booster?
GigAI Audio Volume Booster raises (or lowers) a recording's loudness in your browser with true gain processing and a clipping-aware preview - not a fake slider. Decode, adjust, re-encode to MP3 or lossless WAV locally. The recording never leaves your device.
The GigAI Audio Volume Booster runs on the native Web Audio engine your browser already ships with, so it can decode a clip, measure its true peak, and apply an exact gain to every sample without ever sending your audio to a server. A voice memo taped across a room, a song exported several dB too quiet, an interview where one mic sat low, a video's audio track that plays too soft, all share the same fix: they need more level. Reaching for a full DAW just to turn something up is overkill, and most "volume booster" sites make you upload the file first. Here you drop your file, drag the gain slider to the number of decibels you want to add (or subtract), and the tool shows you the source's current peak and exactly how many dB of headroom you have before it would clip. Turn on "prevent clipping" and the boost is automatically capped at that safe ceiling, so even a heavy lift stays clean. Turn it off and you can push past the ceiling deliberately, with the samples hard-clamped to prevent digital overflow and an honest warning that some peaks were flattened. When it finishes you get a preview player to confirm it sounds right and the measured before/after peak, then download a lossless 16-bit WAV to keep every sample for further editing or an MP3 encoded locally in your browser for a smaller, share-ready file. Because everything is client-side there's no upload wait and no privacy tradeoff: personal recordings, unreleased mixes and confidential interviews never leave your machine. Be honest about what this is: it multiplies the whole signal by one gain factor to make it louder or quieter and clamps safely. It is not a compressor or a loudness maximiser that squeezes dynamics to sound "bigger," it can't un-clip audio that was already recorded too hot, and dB gain is not the same as the LUFS integrated-loudness spec streaming platforms measure. Close the tab and every sample is gone.

How to use the audio volume booster
- 1
Drop your audio
Drag an MP3, WAV, M4A, OGG or FLAC onto the workspace, or click to browse. It's decoded locally and you'll see its waveform, duration and current peak level right away.
- 2
Set the gain in dB
Drag the slider up to make it louder or down to make it quieter. The live readout shows the exact dB and how much clean headroom you have before clipping.
- 3
Keep the clip guard on (or push past)
Leave 'prevent clipping' enabled to auto-cap the boost at the safe maximum. Turn it off only if you want to drive past the ceiling deliberately, the tool clamps peaks and warns you when it does.
- 4
Preview and boost
Press Boost volume. The whole track is re-gained on your device in one fast pass, then plays in a preview player so you can confirm it's louder and still clean.
- 5
Download or start over
Check the before/after peak, download a lossless WAV or a browser-encoded MP3, or reset and try a different amount.
What Audio Volume Booster includes
Boost or cut by exact decibels
Drag one slider to add the precise gain you want (a gentle +3 dB or a big +12 dB lift for a quiet clip) or go negative to pull a track that's too hot back down. The exact dB is always on screen, no guesswork.
Clip protection built in
The tool measures your source's true peak and shows the headroom you have before a boost would distort. Leave 'prevent clipping' on and any lift is capped at that safe ceiling, so a loud boost never turns into crackly digital overflow.
Live headroom readout
See the current peak in dBFS and the maximum clean gain available before you commit, so you know instantly whether you can add 3 dB or 10, and whether the level you asked for will stay clean.
Preview before you download
The boosted result plays right in the page on a waveform player, so you confirm it's loud enough and nothing distorts before you export, the safety net a command-line 'gain' filter never gives you.
Lossless WAV or local MP3
Export a clean 16-bit PCM WAV to keep every sample for further editing, or an MP3 encoded entirely in your browser for a smaller share-ready file. Neither path loads any heavyweight codec.
100% private, nothing uploaded
Decoding, measuring, gaining and encoding all happen on your device with the native Web Audio engine. Voice memos, interviews and unreleased mixes are never uploaded, stored or logged.
Why use our audio volume booster
Rescue a recording that's too quiet
A voice memo taped across a room or a bounce that came out low is painful at normal volume. Add the dB you need with the clip guard on and it lifts to a full, clean level in one pass. No DAW, no upload.
Never distort by accident
Most boosters just multiply the signal and let it clip. Here you see your headroom and can cap the boost at the safe maximum, so a heavy lift stays clean instead of turning into crackle you can't undo.
Turn things down too, precisely
Gain works both ways. Pull a hot clip back by an exact number of decibels to sit it under a voiceover or match it to quieter material, the same one slider, in reverse.
No upload wait, no privacy tradeoff
Server boosters make you upload the file first and trust them with it. Here the audio never leaves your browser, so there's no upload bar and nothing to trust, safe for private or confidential recordings.
Built for the way you work
From quick one-off fixes to daily workflows, see how people put this tool to use.
- Podcaster / Interviewer
Lift a buried guest track
One guest recorded far quieter than the host. Add the dB needed with the clip guard on to bring their track up to a comfortable, clean level before you mix, without touching the louder tracks.
- Content creator
Make a quiet video's audio louder
Extracted audio that plays too soft under a voiceover or on phone speakers. Boost it by a precise amount, preview it, and drop the louder WAV back into your edit.
- Musician / Producer
Raise a low export to reference level
A bounce came out several dB under where it should sit. Push it up to just below full scale with clipping protection so you get a full-level reference without re-exporting from the session.
- Privacy-conscious user
Boost a sensitive recording locally
A confidential memo or personal voice note that's too quiet shouldn't be uploaded to a stranger's server to be amplified. Do it entirely in your browser so nothing ever leaves the device.

Common problems, solved
Hit a snag? Here are quick fixes for the issues people run into most.
It barely got louder even though I set a big boost.
'Prevent clipping' capped the gain because your source already peaks near full scale, there's little clean headroom to add. Check the headroom readout for the real maximum. If you need it louder still, the source's own peak is the limit. Reduce that peak first (re-export lower) or accept some clamped peaks by turning the guard off.
The boosted audio sounds crackly or distorted.
That's clipping. You likely turned the guard off and pushed past the headroom, so peaks were hard-clamped. Turn 'prevent clipping' back on and re-run for a clean lift. If the distortion was already in the original file, boosting can't remove it. The source itself is clipped.
The file won't load or shows a decode error.
The browser couldn't decode that codec natively, most often a niche or DRM-protected file. Try a standard MP3, WAV, M4A or OGG. If it's an exotic format, convert it first with the Audio Converter, then boost the result here.
The tab is slow or ran out of memory on a big file.
In-browser audio holds the whole decoded track in RAM. Close other heavy tabs and retry. If it still struggles, the file is likely too large for this device. Trim it into parts first, or boost on a machine with more memory.
Get the most out of it
Leave 'prevent clipping' on for anything you care about. It gets you the loudest clean result and takes the guesswork out of how far you can push.
Watch the headroom readout: if it says you only have +2 dB of clean gain, the source is already near full scale and a bigger boost will either be capped or start clamping peaks.
Boosting raises noise too. If a recording is quiet because of a distant mic, expect the hiss to come up with the voice, capture closer next time for a cleaner lift.
Use a small negative gain (a dB or two) to gently duck a clip under narration instead of fighting it in your editor.
Keep a lossless WAV as your master if you'll edit further, and only encode to MP3 as the final step so you don't stack lossy generations.
What's new
