Make quiet audio louder.
Without making it complicated.

Anyone who regularly deals with quiet or uneven sound and does not want to fire up a heavy editor for a one-minute task.

Podcast and interview clips where one person is much quieter than the other. Screen recordings and tutorials with weak system audio. Old voice notes or phone videos that need a simple volume lift before you share them. Music or dialogue demos that sit too low next to other tracks. In all of these cases you often only need gain, a soft limiter, and a clean export — not a full project session.

Sound Booster is also useful when you are on a machine that is not yours, or when you simply prefer not to install desktop software. Open the page, drop the file, adjust, download, and close the tab.

Creators who strip vocals for karaoke or practice tracks, editors who check loudness before publishing, producers who boost bass or shape EQ on a laptop, and social teams who need a quick visualizer or a clean audio pull from a video — all of them can stay in the same toolkit without switching apps.

A podcast with more than one speaker rarely has even volume. One guest sits too far from the mic and sounds quiet. Another leans in and almost clips the recording. The same thing happens in voiceovers: a loud line right after a near-whisper.

For the listener, that means constant volume fiddling. Soft parts disappear; loud parts jump out. Leveling the track fixes this — raise the quiet sections, gently hold back the peaks, and keep the whole file consistent from start to finish.

Normalize is built for that. Instead of guessing a gain value, it looks at the loudest peak and brings the whole recording up to a usable level without pushing it into hard clipping. Soft clip can still help if you need a bit more headroom without harsh distortion.

Use it for interviews, multi-guest shows, screen recordings with uneven system audio, or any clip where the dynamics feel uneven and you want one steady listening level.
