What is Tuber Transpose?
Tuber Transpose is a Chrome extension that changes the key, fine pitch and speed of music playing in your browser in real time. It helps singers and live streamers fit backing tracks to their vocal range while controlling tempo and key independently.
Sound familiar?
A viewer requests a song. The key does not fit you. You either decline, or push through and deliver a bad performance. Both cost you viewers.
The fix takes two seconds
Move the slider and the audio plays in the new key instantly. Tempo stays intact, nothing to install.
Transpose
−12 to +12 semitones, with the interval name shown. Tempo never changes.
Fine pitch
−50 to +50 cents. Closes the last small gap between the backing track and your voice.
Speed
25% to 200%. Pitch is preserved; enter a BPM and it works out the new tempo.
Per-song memory
Set it once. Every time you come back to that song, your setting is already there.
Voice profiles
Presets built around your own vocal range, applied in one click.
Keyboard shortcuts
Change key without looking at the panel. Keep your hand on the mic.
What is inside the extension?
Manage the main controls, personal voice profiles, song history and stream settings from one panel.
Where it works
YouTube, YouTube Music, Spotify, SoundCloud, Bandcamp, Deezer, Mixcloud and fizy. Any other site can be enabled with one click.
Spotify and Deezer protect their audio with DRM, so tab capture mode is used there; results vary with the mix.
