Cuando canto bajan los cerros: An initiative for interface development informed by a Latin-American context

This text1 describes the design of an interface informed by the context of experimental electronic sound artists that affords [1] the use of movement to control variations on the signal produced by a performer. Its main purpose is to activate new formats of interaction between Latin-American vernacular vocal performers and technology oriented performers by increasing their range of choices for gesture related control. This interface attempts to generate a gestural language appropriate or relevant to the socio-cultural environment for which is created. The interface processes the audio signal received from a vocalist/performer by sensing and mapping in the digital domain the movement of the performer's hands in four independent electric sensing fields, each corresponding to one kind of processing: sample loop recording and playback, reverberation, loop delay or repetition, and basic frequency filtering techniques.
