Quick answer

Before Sample rate, back up the original, confirm format/size/quality requirements and close programs that lock the file. Sample rate sets the frequency ceiling; 44.1/48kHz covers human hearing.

Why it matters

Poor preparation leads to overwrites, failures and rework.

44.1kHz is the music standard.

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

  • 44.1kHz is the music standard.
  • 48kHz is common for video.
