What is Volume Booster?
The Audio Volume Booster increases the volume of your audio files by up to 5 times. Perfect for making quiet recordings, old videos, or downloaded audio louder and more audible. Simply upload your file and boost to the desired level.
How does Volume Booster work?
This tool uses the Web Audio API to amplify your audio signal. The boosting process multiplies the amplitude of the audio waveform. At moderate levels, this produces clean, louder audio. At extreme levels, it may introduce distortion if the original audio already has high volume.

Frequently Asked Questions
Will boosting distort my audio?
It depends on the original volume. If your audio is already loud, boosting may cause clipping and distortion. Watch the meter and reduce boost if you see red.
What is the maximum boost level?
You can boost up to 5x. However, most audio sounds best at 1.5-3x boost. Higher levels are useful for very quiet recordings.
Does boosting improve quality?
No. Boosting amplifies the existing audio. It cannot improve quality. Quiet audio becomes louder but retains any background noise.
Is my audio file uploaded to a server?
No. All processing happens in your browser using the Web Audio API. Your files never leave your device.
What is clipping?
Clipping occurs when the audio signal exceeds the maximum level. It sounds distorted and harsh. Watch the volume meter to avoid clipping.
Should I normalize or boost first?
Normalize first to bring the audio to maximum volume without clipping, then boost if more volume is needed.
