HOW TO BOOST AUDIO

2. Pick a gain such as 1.25× or 1.5×.
3. Press BOOST.
4. Preview OUT, then DOWNLOAD.
GAIN EXPLAINED
1.0× keeps the same volume.
1.5× makes samples 50% louder.
0.5× reduces volume by half.
3.0× is strong and may distort.
CLIPPING WARNING
Boosting can push peaks too high.
Distortion means clipping is happening.
Reduce gain and boost again.
Try 1.25× before 2.0×.
OUTPUT FORMAT
The boosted file downloads as WAV.
WAV is larger than MP3 or OGG.
Use converter pages after boosting if needed.
SUPPORTED INPUT
MP3, WAV and OGG are the main intended formats.
Other browser-supported audio may also decode.
Unsupported files show a decode error.
BOOSTED WAV OUTPUT
The export is a browser-created WAV file.
WAV can be larger than the original audio.
This is normal for compatibility output.
SAFE GAIN CHOICES
Use 1.25× for a light boost.
Use 1.5× for a clear lift.
Use 2.0× only when audio is very quiet.
Use 0.5× to reduce volume.
NO UPLOADS
Audio stays on the device during boosting.
The browser creates a temporary blob for download.
Reloading the page removes temporary outputs.
PHONE AND TABLET
Use CHOOSE FILE for mobile uploads.
Shorter audio is safer on older phones.
Large files can use more memory.
DESKTOP
Drag an audio file onto the drop panel.
Use ESC to return to the booster screen.
Use arrow keys to move through help pages.
COMMON USE CASES

TROUBLESHOOTING
