Magic Voice Changer is for creating altered voice recordings, whether you want to change a new recording or work with an existing audio clip. It offers more than 25 effects and also supports creating voice from text.
When creating a transformed voice recording
Record your voice in the app, then apply an effect to change how it sounds. Options named in the description include robot, alien, zombie, and helium, as well as chipmunk and underwater-creature styles. The range supports making recordings with different character-like or altered voices, without requiring an imported audio file.
When working with existing audio
If the sound is already saved as an audio file, import it to apply effects rather than recording it again. The app describes this option for existing recordings and sound clips, so both newly recorded speech and imported audio can be modified. The description also lists text-to-voice creation as another way to produce voice content.
When sharing or using a recording on the device
Once a voice recording has been modified, share it with friends through other apps. You can also set a modified recording as the device's ringtone, notification sound, or alarm. These options let the recording be shared or assigned to one of those sound uses. The app is described as having a simple, intuitive interface and a futuristic design.
