How to convert WAV to FLAC

  1. Drop the audio.
  2. Nothing to choose.
  3. Press Convert and download.

What happens to your file

The PCM samples are packed with FLAC: nothing is thrown away, the file is typically 50–60% of the WAV, and any player decodes it back to the identical samples.

An MP3 or M4A is not accepted here on purpose: wrapping a lossy file in FLAC makes it larger and no better.

Questions

Is FLAC really lossless?

Yes — decode it and you get the WAV back, bit for bit. It is the format archives and audiophiles keep.

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": "flac"
    }
  }'

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.
