Pitch Shift, Transpose Key & Speed Control for YouTube – KeyPitch

Transpose, adjust pitch and speed, loop any passage, and work on your music right on YouTube and YouTube Music. Learn solos by ear, master tricky passages, train your voice, or prepare your lessons. Your music, your key, your pace. KeyPitch turns your browser into a real-time digital audio workstation (DAW) and keeps your saved tracks and settings from one session to the next. 🚀 Core Features 1. Key Transposition Change the key of a track without altering its tempo. • Semitone adjustment: from -12 to +12. • Ideal for: Adapting a song to your vocal range or playing in a different key without changing chord shapes. 2. Precise Pitch Control (Hz) Unlike classic transposition, pitch adjustment is fine-grained and continuous. • Surgical precision: Adjust frequency from 415.3 Hz to 466.2 Hz (around the standard 440 Hz tuning). • Ideal for: Microtonal tuning, pitch correction, or matching slightly detuned recordings. 3. Tempo Control (Time Stretching) Speed up or slow down playback from 0.25× to 4.00× without affecting pitch. • Total smoothness: High-quality algorithm with no audible artifacts. • Ideal for: Analyzing complex solos or progressively practicing fast passages. 4. Immersion: Reverb & 8D Audio • Reverb (0–100%): Recreate the acoustics of a concert hall or studio to add depth and warmth to a “dry” sound. • 8D Spatial Mode: Create dynamic rotational movement. The sound feels like it’s moving around your head (best experienced with headphones). 5. 10-Band Equalizer (EQ) — New Shape your sound with precision, from deep lows to the finest highs. • 10 frequency bands: Adjust each area of the spectrum independently. • 6 ready-to-use presets: Bass Boost, Vocal Boost, Treble Boost, Warm, Bright, and Loudness. • Ideal for: Bringing out a bass line to transcribe it, pushing vocals forward to practice a song, or tailoring the sound to your headphones and speakers. 6. Precision A/B Looping — Improved Define point A and point B with millisecond accuracy. • More intuitive: The A/B Loop has been redesigned to be simpler and faster to use. • Modes: Infinite loop or single loop. • Savable: Save your loops to your library and get them back exactly as they were (see below). • Use case: Repeat a difficult section until it's perfectly mastered. 7. Your Personal Library (Save & Recall in One Click) Never set up the same track twice. • Save everything: Store any track together with the settings you tuned for it. • One-click recall: Reopen a saved track in your next session and everything is exactly where you left it. • A/B loops (New): Save only the passage you want to work on — the chorus, for example — together with all its settings. In your next session, reopen exactly that passage, with exactly the same settings. • Folders: Create folders to sort your tracks however you like. A teacher can, for example, create one folder per student and rename it with their name, making it effortless to find the right material during a lesson. • 100% local storage: Your library lives in your browser, on your machine. Nothing is stored on our side. Close the tab, close your browser, restart your computer, or update KeyPitch — your library will still be there, exactly as you left it. 8. Studio Mode (Side Panel) — New A workspace designed for comfort, even during long sessions. • Side panel: KeyPitch opens in Chrome's side panel and stays visible right next to your video. • Theater mode: The YouTube video switches to theater mode for a better use of your screen space. • Ideal for: Keeping all your controls in view while you play, and working more comfortably. 9. My Space: Your Practice Stats — New A new “My Space” tab in the side panel gathers all your practice statistics, to help you build real habits and grow as an artist. • Streaks: Your current day streak and your best streak. • Practice time: Over the last 7 days and all time. • Activity: Number of tracks practiced, active days, and more. • 100% local: Your stats are stored only in your browser, on your machine. 🎨 A Unique Modular Interface Unlike traditional extensions, KeyPitch offers a fully customizable workspace: • Drag & Drop: Freely rearrange each module to match your workflow. • Automatic memory: The interface remembers your preferred layout. • Modern design: Dark glassmorphism look, elegant and optimized to reduce eye strain during studio sessions or late-night use. 🌍 Now Available in Your Language The KeyPitch popup is now fully translated into every language supported by the Chrome Web Store, so you can work in the language you are most comfortable with. • Automatic: KeyPitch follows your browser language — nothing to configure. • Spotted a clumsy translation?

A singer can move a song into their own key, a guitarist can learn a fast solo by ear at their own pace, and a teacher can prepare an entire lesson in a single extension, without juggling several apps. 🔒 Technology & Privacy • Professional-grade quality: Ultra-low-latency DSP (Digital Signal Processing) engine for smooth real-time processing. • 100% Local: All audio processing happens directly in your browser. • Privacy-first: No data collection, no account required, no cookies. 🐛 Bug Fixes Thanks to your feedback, we fixed the desynchronization bug between the playback speed of the YouTube tab and the speed displayed in the KeyPitch popup.
