What is
Volume Booster Online helps make quiet audio louder. It is useful for voice notes, recordings, interviews, lectures, podcasts, and clips that sound too low before sharing.
The tool lets you choose a boost level, preview the result, use soft limiting to reduce harsh peaks, and export a new MP3 or WAV file.
How to
Quality notes
Volume boosting multiplies the audio signal. If the boost is too high, loud parts can hit the digital ceiling and create clipping distortion. The soft limiter option keeps the audio louder while reducing harsh clipping on peaks.
For quiet voice recordings, moderate boosts such as 150%, 200%, or 300% usually work better than forcing the maximum setting. For already loud music, use smaller boosts and preview carefully before creating the output file.
Your selected audio is processed on your device. For large files, keep the page open and avoid running too many other applications until the louder version is ready.
