Audio Volume Booster
Increase the volume of MP3, WAV, OGG, M4A and FLAC audio directly in your browser. Choose a boost level, preview the result and download the louder audio file as WAV or MP3.
The original file is not modified. Strong boosts may increase perceived loudness while also making clipping or distortion more noticeable on already loud recordings. Export as WAV or MP3.
Boost audio volume online
Audio Volume Booster increases the playback level of a recording without changing the original file. Choose a boost level, process the audio locally in your browser and download a new WAV or MP3 copy.
How to increase audio volume
1. Add your audio file
Drop an MP3, WAV, OGG, M4A, AAC or FLAC file into the upload area. The browser prepares the file locally.
2. Choose the boost level
Select a moderate or stronger volume increase depending on how quiet the source recording is. Starting around 125% or 150% is a practical way to compare the result.
3. Preview the boosted audio
Use Preview Boosted Audio to listen before creating the downloadable copy. Compare the result with the original and reduce the boost if you hear distortion.
4. Boost and download
Click Boost Audio to render the processed file, then download the new WAV or MP3 copy. The original recording remains unchanged.
What is audio volume boosting?
Volume boosting applies additional gain to an audio signal so a quiet recording can be played at a higher level. The available headroom depends on the original recording, so very strong boosts can make clipping more noticeable.
How much should you boost an audio file?
A small increase is usually easier to keep clean. Try 125% or 150% first, then move higher when the source is genuinely quiet. If the recording already contains peaks close to the maximum level, a large gain increase may cause audible distortion.
Volume boosting vs audio compression
Volume boosting changes the signal level, while compression changes the dynamic range and can make quieter and louder parts more consistent. The two processes solve different problems and may sometimes be used together.
Privacy and local processing
Audio volume processing is performed locally in your browser. Your selected recording is not intentionally uploaded to a NeroTool processing server.
Practical volume boosting tips
- Keep the original recording before processing.
- Start with a moderate boost and listen for clipping.
- Compare speech clarity and background noise before choosing a stronger level.
- Use the downloaded WAV or MP3 as a new copy rather than overwriting the source.
