Voice Synth is an advanced live instrument that allows users to generate remarkable voices, choirs, rhythms, sounds, and immersive soundscapes based on their individual vocal input. Users can engage with the device by speaking, singing, humming, or beatboxing into the microphone, enabling them to instantly manipulate their voice into numerous variations, including that of a baby, a tenor, a pop star enhanced with AutoPitch, or even a robot reminiscent of Cylon or Dalek. Moreover, it can emulate a range of choirs, from church harmonies to close-knit vocal ensembles, as well as mimic different animals, from birds to dogs and lions, along with musical instruments like organs, guitars, and vibrant bass sounds to percussion. The application comes equipped with over 200 factory presets, providing a solid foundation for creativity. Users can choose between two distinct play modes: live mode for real-time expression and sampler mode for playback of recorded sounds. The vocoder within the app offers three unique voice modes—natural, robot, and breath—while the Vocoder Designer empowers users to create personalized vocoders using four oscillators and various synthesis tools. Additional functionalities include a pitch tracker, formant shifter, pitch and scale shifter, classic effects, and stroboscopic vocoder gating, making it a versatile tool for any music enthusiast or professional. With its expansive range of features, Voice Synth truly stands out as an innovative solution for transforming vocal creativity.
