Why it matters
Get the shortest path working before optimizing.
44.1kHz is the music standard.
Step by step
- Back up the original and confirm target format/duration/size.
- Select start/end on the waveform and audition the selection.
- Trim leading/trailing silence but keep natural attack/tail.
- Export WAV/target format and check duration/loudness/clipping.
- 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.
