How to mp3 to wav

  1. Sign in — 500 free credits a month.
  2. Drop the audio in the workbench.
  3. 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 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 or flac 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.
