How to trim audio

  1. Drop the audio.
  2. Type the start and end seconds; pick a format.
  3. Press Trim and download.

What happens to your file

The part between your two seconds is decoded and written in the format you chose; WAV and FLAC keep every sample, MP3 and M4A re-encode at a quality most people cannot tell apart.

Nothing outside the two seconds is in the result; the original is untouched.

Questions

How do I make an iPhone ringtone?

Trim to under 30 seconds, save as M4A, rename the file to .m4r and add it through iTunes or the Finder.

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.

Do this in code

  -H "Authorization: Bearer $FYLANE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "file_id": "<file id>",
    "operation": "audio.trim",
    "options": {
      "format": "mp3"
    }
  }'

The same operation, audio.trim — The seconds you name, in the format you name. Upload first with the quickstart; every option is on the operations page. 500 free credits a month, then $5 per thousand.
