Karaoke is a great way to express yourself and share your songs with the world. But when you record your song, the sound can be a little too loud and it can be hard to hear yourself. With the Karaoke Pitch Changer app, you can adjust the pitch and tempo to make it easier to listen to your recordings. It can also be used to change the pitch and tempo of songs in an MP3 format.

When you first open the app, it will ask you to log in with your Google account. If you’re already logged in, you can start recording and the app will automatically open in the background.
