Our volume booster increases the loudness of audio files beyond their original level. It works by amplifying the audio signal using a gain node in the Web Audio API. You can boost volume up to 300%.
This is especially useful for quiet recordings, videos with low audio, podcasts recorded at conservative levels, or any content that needs extra punch.
Moderate boosting (up to 150%) preserves quality. Extreme boosting can cause clipping and distortion.
Up to 300% of the original volume. Beyond that, distortion becomes significant.
