About this tool
About Audio Volume Booster
Enter any volume level from 10% to 400% or use the linked slider. A limiter reduces hard clipping before the processed MP3 is made available for preview and download.
This tool is available for browser processing. The main operation runs on your device when supported by the browser and selected format.
When to use Audio Volume Booster
Use it when a voice memo, interview or downloaded clip is too quiet compared with the rest of a project. Raise the level carefully and listen for clipping rather than simply choosing the largest boost.
How to use this tool
- Add the audio file and wait for its waveform or duration to load.
- Adjust the gain or volume control in small steps.
- Preview loud sections and pauses to check for clipping, hiss or distortion.
- Export the result and compare it with the original on the same device.
Loudness and privacy
Audio output depends on the source codec, sample rate, channels, bitrate and selected format. Long recordings use browser memory during decoding and encoding, so preview the export and keep the original. Supported processing runs locally in the browser when available.
