Using the Sound Editor
Scratch has a built-in sound editor accessible from the Sounds tab.
What You Can Do
- Trim — cut out unwanted silence at the start or end.
- Reverse — plays the sound backwards (cool alien/ghost effect).
- Faster / Slower — changes the playback speed.
- Echo / Robot / Louder / Softer — one-click audio effects.
How to Edit
- Go to the Sounds tab and click a sound.
- Click and drag on the waveform to select a region.
- Click an effect button to apply it to the selected region.
