If you’ve ever wanted to sing in public, but know that your voice is a little pitchy, then this is the gadget you need. Singtrix is a karaoke machine on steroids, not just capable of removing vocal tracks so you can sing along, but actually improving your voice.

The system adds a variety of vocal effects, ranging from pitch correction to thick vocal harmonies to make anyone sound on key. While it won’t make a horrible singer into a pro, its makers say that “bad singers will sound good, good singers sound great, and great singers sound like rock stars.”

It’s also loaded with all kinds of cool effects, like robot voices, autotuning, delays, and the ability to raise or lower the pitch of your voice. Check out just how much the system can change an ordinary voice:
