How to convert MP3 to WAV

Sign in — 500 free credits a month.
Drop the audio in the workbench.
Run Convert and download the WAV.

What happens to your file

The MP3 is decoded to raw samples and written as 16-bit PCM WAV at the same sample rate. The file is around ten times larger — that is what uncompressed means.

Detail the MP3 already discarded is not restored; WAV stops further loss when you edit and re-save.

Questions

Why would I want WAV?

Editing, sampling, phone systems and some upload forms require PCM. For listening, MP3 is fine.

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 — free What 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.convert",
    "options": {
      "format": "wav"
    }
  }'

The same operation, audio.convert — mp3, wav, aac, flac, ogg, opus or aiff out of whatever came in. Upload first with the quickstart; every option is on the operations page. 500 free credits a month, then $5 per thousand.
