Easy Transpose by @ffgcvs

About

Shift the pitch of any YouTube video up or down in semitones — without speeding it up or slowing it down.

Perfect for:
• Singers — move a song into your vocal range before practicing
• Guitarists — match a song to your capo position or alternate tuning
• Pianists — transpose a piece into an easier key
• Music students — train your ear across different keys

How it works
A small dark panel appears at the top-right of the YouTube player. Click − or + to change the key, or use the keyboard shortcuts below. Pitch is saved per video, so when you come back to the same song, your setting is still there.

Keyboard shortcuts
• Shift + ↑  — raise pitch
• Shift + ↓  — lower pitch
• Shift + 0  — reset to original

Quality
Audio is processed locally using a streaming pitch-shift algorithm. No audio leaves your browser, and there is no delay vs. the video.

Privacy
• 100% local processing — no audio or usage data is sent anywhere
• Preferences are stored in your browser only, via chrome.storage
• No tracking, no analytics, no accounts

Range: ±12 semitones. Works in fullscreen and theater mode. Remembers your last pitch for each video you've adjusted.

Limitations
• Works on standard YouTube videos; DRM-protected premium content and some live streams may behave differently
• Large pitch shifts (beyond ±7) start to sound processed — this is a limitation of the streaming algorithm
