Sound from Loudness
Synopsis
Exploring the sound as a worldbuilding element, to propose an interactive interface where the user constructs and transforms the sound ambience in real time through voice. Using Pure Data as a processor, the system receives the signal coming from the sound input through a microphone, and process its intensity generating different states of an acoustic dynamic system. The result is a sound field that oscilates between spaces of calmness, activity and chaos, reflecting the relation between control, expression and instability. Loudness = Ambient Soft - calm Soft - Chaos Normal - active vs Normal - Active Loud - chaos Loud - Calm
Sound From Loudness
Main Objective and Outcome
Objetive: Explore and research how does sound works as a worldbuilding element while the user can influence the system through interaction. While exploring the concept of interface where the control isnt a button, but an intesity of sound provocaded vocally. The loudness of the voice. Outcome: Interactive interface that answers in real time to the input of the user and creates an acoustic space with different layers.

Questions to be explored
How can this be distributed physically? Speakers vs Headphones Should the voice be continuous or just a trigger? How does Pure Data read loudness from the input/microphone? How to balance between samples and Pure Data generated sound? Can we do panoramic automations?
Janet Cardiff
Janet Cardiff is a Canadian contemporary artist renowned for her sound installations and “audio walks,” which explore the spatial perception of sound. Also known for immersive works that combine recorded narration, music, and environmental sounds to create three-dimensional experiences. Her pieces blur the boundary between reality and auditory illusion, inviting the listener to physically move through sound. Her pioneering use of binaural recording in “audio walks” creates a vivid sense of spatial presence.

Ryoji Ikeda
Micro / Macro 2015-2022
Ryoji Ikeda’s Micro/Macro (2015) explores the relationship between human, micro, and macro scales using data, mathematics, and physics, contrasting the microscopic (projected on the floor) with the macro (projected on a large screen). The installation requires no scientific background, immersing visitors in an experience that highlights scale and perception. In 2022, Ikeda expanded this concept with the Micro/Macro Pavilion, a minimalist structure housing an LED room that displays scientific data illustrating invisible connections in everyday life, such as the links between mobile phones, satellites, and space. Blending architecture, installation, and sound, the pavilion becomes an immersive sensory exploration.
Although the project described here does not seek an artistic–scientific approach of this kind, Ikeda’s spatial representation and sensory research are important to understanding and inspiring the exhibition development of the project.
Zach Lieberman
Zach Lieberman is an American artist, creative coder, and educator known for exploring the intersection between art and technology. Based in New York, he creates interactive and performative works that translate human gestures into visual and sonic experiences. He is considered a central figure in the international creative coding community.

Rafael Lozano-Hemmer
Rafael Lozano-Hemmer is a Mexican-Canadian electronic artist living and working in Montreal, Quebec, Canada. He creates interactive works. He emphasizes that his installations are incomplete without public participation, treating audience participation as an essential material in his creative process.
