Boost quiet recordings or ease loud peaks with live preview before you save.

or drop a file here

MP3, WAV, OGG, M4A, AAC, FLAC, or WebM — up to 100 MB. Processing stays in your browser.

Load a clip, open Volume, and raise or lower gain while you listen. Preview follows the waveform playhead so you can judge loudness before you save the louder or softer file.

How to change audio volume online

Volume (gain) scales how loud a track plays and exports. Quiet voice notes often need a boost; clipped streams may need a reduction. This changer previews live, then bakes your preference when you save.

  1. Upload audio — drop MP3, WAV, or another supported file.
  2. Adjust Volume — move the gain control while playing. Watch levels with your ear, not only the number.
  3. Combine if needed — trim edges or tame tone with the Equalizer before final export.
  4. Save — download in your preferred format. Editing stays on your device.

Gain vs normalize vs limiter

Approach What it does Best for
Volume / gain Multiplies level by a constant Simple louder/quieter fixes
Normalize (Effects) Raises peaks toward a target ceiling Under-recorded takes that need max headroom
Compressor / limiter Controls dynamic range Uneven speech and sudden spikes

Start with Volume for a quick change. If the take is soft overall, try Normalize from Effects. If words jump from whisper to shout, use Compressor after a modest gain bump.

Avoid distortion when boosting

  • Raise gain in small steps and listen for crackling on the loudest syllables.
  • If peaks already hit the ceiling, lower first or use a hard limiter / compressor instead of raw gain.
  • Pair with the Audio Equalizer to cut muddy low end before boosting — perceived loudness often improves without extra clipping.

Privacy

Gain preview uses Web Audio in the browser. Exports may encode on-device. ShoutingNow does not upload your clip for volume processing.

Common questions

Quick answers before you start calculating.

Open the file in this Volume Changer, raise the Volume control while playing, then Save. If it still sounds soft, try Normalize under Effects after a careful listen for clipping.
