Ultimate Voice Changer Lite is the only app that has "dynamic pitch shifting" which lets you change the pitch of your voice in real time while you record. When you have the "dynamic pitch shifting" effect selected you can move the slider back and forth while you record, and morph yourself from an ogre into a chipmunk in the same recording. Send it to your friends and they will be amazed!
Other cool effects that are only included in the full version of Ultimate Voice Changer are echo, static, chipmunk, ogre, anti-gravity, bird, robot, cyborg, distortion, phaser, and space.
So have some fun morphing your voice and sending your creations to your friends. Happy morphing!
