# Boost quiet audio free, no upload
Cutshed Volume booster is a free browser tool that runs on this device. Peak-normalize a recording or boost it by a fixed amount, then download a WAV.
Raise a quiet voice note to a sensible peak, or add a fixed boost. Peaks that would pass full scale are clipped so the file stays valid.
## How to use it
- Peak normalize finds the loudest sample and scales the file so that sample lands near −1 dB. That is the right move for a voice memo that was recorded too low and has no huge spikes.
- +6 dB and +12 dB multiply every sample by a fixed gain. If the take is already loud, those peaks flatten. You will hear that as a harder edge, not as more detail.
- The download is 16-bit WAV at the decoded sample rate. This is not a loudness-unit normalizer and it does not match two files to each other. Run it once, then stop.
## Tips
- Normalize a quiet interview before you run the noise remover. RNNoise behaves better when the voice is not a whisper in the noise floor.
- Do not stack +12 dB twice. Clip once, then leave it.
- If the meter looks fine but the voice still feels quiet next to music, the issue is loudness, not peak. Mix that in your editor.
## FAQ
- Will this fix distortion that is already in the file?
No. Clipping that was recorded is still clipping. Gain only changes the level of what is there.
- Why WAV and not MP3?
A level change should not add another lossy encode. Convert afterwards if you need a smaller file.
- Is the boost uploaded for processing?
No. Web Audio decodes the file in the tab and writes the WAV there.
