The eMic is a gestural controller for live vocal performance and electronic processing.
The eMic is designed as a means to extend the voice in performance via electronic processing technologies. It aims to address the desire for the vocalist using amplification to increase the level of control over their own sound in the sound system and to harness the audio processing technologies once confined to the recording studio. It aims to do this in a way that is not only musically responsive to the performer, but also visually engaging for the audience.
