How to convert M4A to MP3

  1. Drop the audio.
  2. Pick a bitrate.
  3. Press Convert and download.

What happens to your file

The AAC audio is decoded and re-encoded as MP3 at your bitrate. Both are lossy, so a sliver is lost in the hop; at 192 kbps nobody hears it.

Apple Music tracks with DRM (older .m4p) cannot be converted by anyone.

Questions

Which bitrate?

128 for speech and small files, 192 for music, 320 when the source was lossless.

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": "mp3",
      "bitrate": 192
    }
  }'

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.
