EnglishENBoost audio volume online. Make quiet MP3, WAV, and voice recordings louder from audio or video files, then export — free audio volume booster.

Upload MP3, WAV, M4A, AAC, or video — the browser extracts the track — or paste a URL. Voice memos, phone recordings, and low-level exports are common inputs on this page.
The Volume tab opens first. Raise the slider gradually and preview after each move. Stop when audio sounds clearly louder without clipping or harsh distortion.
Pick MP3, M4A, AAC, or WAV on export. Preview once more on headphones, then sign in to download. Editing stays free in the browser until you save.
Raise quiet speech and recordings, preview before clipping, and finish trim or pitch edits in one browser session.
Copy and defaults focus on boosting quiet speech, music, and field recordings — not just generic level change. The Volume tab opens first so you can raise voice memos, phone captures, and low-level MP3s immediately after upload or URL import.
Boost volume now
Listen in the editor so you boost volume without harsh distortion. Gradual slider moves plus playback preview help you find a louder level that still sounds clean on headphones and laptop speakers.
Preview your boost
Trim dead air on the Trim tab or fix pitch after boosting — same session, same file. Upload audio or extract sound from video once, then chain trim → boost → export without re-uploading to another website.
Open full editor
Upload the MP3, move the volume booster slider up, preview, and export. This page opens on the Volume tab by default. You can also upload video — the browser extracts the audio track before you boost quiet dialogue or music.
Both use the same slider. Volume booster pages emphasize making quiet files louder; volume changer covers increase and decrease equally. Choose booster when SEO and defaults target loudness fixes for memos, podcasts, and low-level recordings.
Too much boost causes clipping. Raise gradually and use preview — lower the slider if you hear distortion. Trimming silence first often lets you boost speech more cleanly because the meter is not fighting long quiet sections.
Edit free in your browser; download after sign-in. Preview as many slider positions as you need, switch to Trim or Pitch tabs in the same session, then export MP3, WAV, M4A, or AAC.
Make voice memos and low-level recordings louder from audio or video, preview before export, and save MP3, WAV, M4A, or AAC.
