Volume booster
Raise a quiet track's level by up to +15 dB — a limiter catches the peaks so the boost doesn't clip and distort.

A volume booster applies clean gain to your audio file, then runs the result through a limiter so the loudest peaks are held below the clipping ceiling. AI-generated songs from Suno often export a few dB quieter than commercial releases, so a bare track can sound thin or distant next to reference material on the same playlist. Instead of re-generating or dragging the file into a DAW just to nudge a fader, you raise the overall level in the browser and get a louder file back in seconds.
Reach for this when the problem is simply "too quiet" rather than "badly mixed." It's the right tool before you upload a track that plays back noticeably softer than everything around it, or when a song is hard to hear on laptop and phone speakers. Keep in mind that gain lifts the entire signal, so any background hiss or hum in the original rises with the music, and a limiter is not a substitute for full mastering — it prevents clipping, it doesn't rebalance the mix.

When to use it
- You exported a Suno song that plays back clearly quieter than the other tracks in your SoundCloud or DistroKid upload batch, and you want its level to match before release.
- A vocal-forward AI song is too soft to make out on phone speakers, so you push it up several dB before sharing the file in Discord or sending it to a collaborator.
- You're layering a quiet instrumental stem in a DAW and want to raise its baseline level first so it sits properly in the mix without maxing out the channel fader.
FAQ
Will boosting cause distortion?
A limiter caps the signal just below full scale, so peaks get gently squeezed instead of clipping. Extreme boosts (+12 dB and up) on already-loud material will still sound compressed.
Boost vs normalize — which do I want?
Use this when one file is simply too quiet. Use the audio normalizer when you want a specific loudness target like -14 LUFS.
How many dB should I actually boost by?
Start small and listen rather than jumping straight to +15 dB. If a track already peaks close to 0 dBFS, most of a big boost just slams the limiter and increases perceived loudness without real headroom, which can flatten the dynamics. A quiet track sitting well below full scale can take a larger lift cleanly, so pick the amount that matches a reference song at the same playback volume instead of pushing to maximum by default.
Does boosting volume lower the audio quality?
The gain math itself is lossless, but boosting raises the noise floor, so any hiss, room tone, or artifacts in the original get louder alongside the music. Heavy limiting can also squash the peaks and reduce dynamic range. To avoid stacking a second quality hit, export to WAV rather than re-encoding to MP3, since a lossy re-encode of an already boosted file adds its own compression artifacts.
Will a boosted track be too loud for Spotify or YouTube?
Major streaming platforms apply loudness normalization on playback — Spotify targets around -14 LUFS — so an over-boosted upload just gets turned down automatically and may end up sounding squashed and lifeless. Boosting is most useful for local files, downloads, and platforms that don't normalize. For streaming you're aiming at a consistent loudness target, not the highest possible peak.
