Pitch Shifting for YouTube Videos

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

  1. Install the extension from the Chrome Web Store
  2. Navigate to a YouTube video on Slow Down
  3. Click the extension icon in your toolbar and enable pitch shifting
  4. Use the on-page controls to adjust pitch

Turn on "Auto-enable on Slow Down" in the extension popup so it activates automatically. The extension works with Chrome, Edge, Brave, Arc, and other Chromium-based browsers.
