Quick answer

Choose Audio metadata by use case and compatibility first, specs second; test locally when possible. ID3 can contain artist/title/GPS; consider stripping before publishing.

Why it matters

Stacked specs do not guarantee fit for your use case.

WAV conversion may drop tags.

Step by step

  1. Back up the original and confirm target format/duration/size.
  2. Select start/end on the waveform and audition the selection.
  3. Trim leading/trailing silence but keep natural attack/tail.
  4. Export WAV/target format and check duration/loudness/clipping.
  5. Keep the original; confirm rights/privacy before publishing.

Common mistakes

  • Cutting the attack/tail so the edit sounds abrupt.
  • Re-encoding MP3 repeatedly and accumulating loss.
  • Exporting too loud and clipping.
  • Publishing unlicensed music/someone's voice.

Checklist

  • Original backed up.
  • Start/end/duration are correct.
  • No clipping/glitches/obvious silence.
  • Format/sample rate/channels match the use.
  • Rights/privacy cleared.

Key facts

  • WAV conversion may drop tags.
  • Remove private info manually.
