About Key Changer

Shift music up or down while it plays in a supported desktop Chrome tab without changing tempo. Key Changer is for singing practice, karaoke and playing along with recordings on sites such as YouTube, Spotify Web and SoundCloud. Adjust pitch from -12 to +12 semitones, or fine tune by 1-cent steps within -50 to +50 cents. The Keep vocals natural option helps preserve vocal timbre as pitch changes. Install the Chrome extension to use it. It is for listening and practice, not audio export, and is currently free in early access.

Hi! Quick story about pizza and founders.

Our Premium pass costs $19. That's one large pizza.

You know what happens after you eat a large pizza? Nothing. It's gone. Maybe some regret.

But $19 on Premium? Your product gets a permanent dofollow backlink from a DR 74 directory. Featured on the homepage. A guaranteed tournament slot.

That listing stays there for years. The pizza? Gone in 20 minutes.

The price is identical. The value is not.

Launch your product, not your calories.
