How to Increase the Volume of a Quiet Audio File Online

Try it now: Volume Booster →

A recording made too far from the microphone, or with input levels set too low, often comes out quieter than it should be. Rather than re-recording, boosting the volume after the fact usually gets it back to a usable, comfortable level.

When you need to boost audio volume

• A voice memo or recording came out much quieter than expected
• A video's audio track needs to be louder before sharing
• Combining clips of different volumes into one consistent-sounding file
• Making a recording easier to hear on devices with quiet speakers

How to boost audio volume, step by step

1. Open the Volume Booster.
2. Upload the quiet audio file.
3. Increase the volume boost and preview the result.
4. Check that the louder audio doesn't distort or clip.
5. Download the boosted audio file.

Tips for boosting volume cleanly

• Preview before committing to a large boost. Pushing volume too high can introduce distortion or clipping, especially on already-loud sections.
• Boost moderately and check the loudest parts of the recording, not just the quiet parts, since a big overall boost affects loud moments too.
• Trim out unwanted sections first with the MP3 Cutter so you're not boosting noise or dead air along with the audio you want.

Common questions

Will boosting volume cause distortion? It can, if pushed too far — always preview the result and back off the boost if loud sections start to sound distorted or clipped.

Can this fix audio that's inconsistently loud throughout? A flat volume boost raises the whole file evenly; it won't fully even out sections that are inconsistently loud relative to each other.

Does this work on any audio file? Upload the audio file you have; the tool applies the volume boost to it directly.
