WHAT THIS TOOL DOES

This tool boosts or reduces audio volume in the browser.

Load MP3, WAV or OGG, set gain, preview the result and download WAV.

The layout is split across input, gain, plan and output pages to stop overlap.

Choose an audio file on page 1, set the gain on page 2, then press BOOST.

Use PLAY IN and PLAY OUT on page 4 to compare the original and boosted audio.

Download appears after the boosted WAV has been created.

1.0× keeps the same volume. 1.25× is a light boost.

1.5× is a stronger lift. 2.0× and above may distort loud audio.

0.5× reduces volume for files that are too loud.

Boosting can push peaks above the safe range.

If the boosted audio sounds harsh or distorted, lower the gain and boost again.

Try 1.25× before using 2.0× or higher.

The boosted result downloads as WAV.

WAV is useful for editing but may be larger than MP3 or OGG.

Use a converter page afterwards if you need MP3 or OGG output.

Use CHOOSE on mobile and tablet to pick audio from storage.

Desktop browsers are better for large files and long recordings.

Shorter audio is safest on older phones.

If decoding fails, try WAV input or another browser.

If boosted audio distorts, reduce the gain and press BOOST again.

Clear removes temporary preview and download links.
