Getting Started

  1. Add a YouTube video by URL or upload an audio file
  2. Use the speed slider to slow down or speed up playback
  3. Add markers at key timestamps to jump back to
  4. Create loops between markers to repeat difficult sections
  5. Adjust pitch/transpose to practice in any key

Pitch Shifting for YouTube Videos

Pitch shifting for uploaded audio files works directly in your browser. For YouTube videos, it needs the free Slow Down extension:

  1. Install the extension for Chrome or Firefox
  2. Navigate to a YouTube video on Slow Down
  3. Click the Slow Down icon in your toolbar to turn on key and vocal controls
  4. Use the on-page controls to adjust pitch

Click the icon again to turn them off. On YouTube, the same icon opens Slow Down in a side panel. The Chrome version also works in Edge, Brave, Arc and other Chromium browsers.

Keyboard Shortcuts

Space Play / Pause
← → Seek 5 seconds, or the step you pick in the player's shortcuts menu
↑ ↓ Adjust speed
Shift + ↑ ↓ Adjust pitch
1-9 Jump to marker

Troubleshooting

Audio not playing

Click the play button — browsers require a user interaction before audio can start.

YouTube pitch extension: no sound after enabling

Try disabling and re-enabling from the extension popup. If the issue persists, refresh the page.

Extension icon not visible

Click the puzzle piece icon in your Chrome toolbar and pin the Slow Down Pitch Shifter extension.
