Ultimate Voice Changer gives you 12 unique voice effects and its 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.
Other cool effects included in this full version of Ultimate Voice Changer are echo, static, chipmunk, ogre, anti-gravity, bird, robot, cyborg, distortion, phaser, and space.
You can also combine different effects to come up with your own unique effect. So have some fun morphing your voice and sending your creations to your friends. Happy morphing!
