How to normalize audio

  1. Drop the audio files.
  2. Pick the output format.
  3. Press Normalize and download.

What happens to your file

The loudness of the whole file is measured the way broadcasters do (EBU R128) and the gain adjusted so it lands at −16 LUFS with peaks held under −1.5 dB — the same recipe podcast hosts and streaming services apply on upload.

It is a level change, not a compressor: quiet passages stay quiet relative to loud ones. A file already at the target comes back unchanged apart from the encode.

Questions

Why do my recordings sound quieter than everything else?

Phones and recorders leave headroom; players do not turn it up. Normalising to the common target makes yours match.

Do it once, not on every form

Fixing a file here means downloading it and going back to the form. The Fylane extension does this work inside the form instead, on the file you already have.

And it keeps the result. The next application that asks for a résumé, a cover letter and a photo fills all three from one tap, each one refitted to what that site accepts.

Your files stay in the browser, encrypted, on your machine. Nothing is uploaded to keep them and nothing is sent anywhere to fill a form.

Filmed from the extension: three upload fields on a job application, filled from one tap.

Add to Chrome — freeWhat it does

Do this in code

curl -X POST https://api.fylane.dev/v1/jobs \
  -H "Authorization: Bearer $FYLANE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "file_id": "<file id>",
    "operation": "audio.normalize",
    "options": {
      "format": "mp3"
    }
  }'

The same operation, audio.normalize — EBU R128 loudness (-16 LUFS) — the broadcast answer to "too quiet". Upload first with the quickstart; every option is on the operations page. 500 free credits a month, then $5 per thousand.
