A useless machine for visualizing sound: just because nowadays everything is purely visual and music makes us feel good.
How do you imagine sound? The first thing that came to my mind was the speakers' cone/diaphragm and how it moves back and forth when playing music. We as a group imagined a wave. Sound waves make air molecules travel toward and away from the source in high and low pressure. The easiest way to visualize these pressure areas is by picturing waves. Low notes have higher amplitudes and wavelengths and high notes the opposite, smaller amplitudes and wavelengths. It is the superposition of both that make our brain perceive sound.
As part of the exercise, we had to ask the rest of the group what they imagined. Some told us to make a speaker and put marbles or sand on top, others thought about concerts so they drew hands clapping when the music started to sound, others imagined a fan with long threads that started running when the sound began. Many ideas.. but still we really liked ours, so we decided to stick to it and make it real.
We looked for references and found that there are quite a lot, from music videos to fancy sculptures; mostly related to art installations (as we imagined): Waves by Daniel Palacios, Sonic Sculptures by Martin Klimas, Crystallize by Tokujin Yoshioka, some others like the "Atari Video Music System" that works like a music visualizer, Milkdrop for making abstract images, CYMATICS video by Nigel Stanford, and so many others.
How will we get there? Well... we decided the wave was going to be formed by a thin fabric, and at the bottom of a light structure we could place fans so when the music began, the fans could start blowing air for the textile to move along with it, and just to add a bit more for pleasure... a line of LEDs that illuminated the piece.
We put our hands into action, Pablo and Laura decided to focus on the coding and Juanita and I, on the physical representation - the structure, fans, and fabric. After two days of hard work, we got it! Although I have to say we imagined it a bit better... we had to place cones for the air to focus on a specific area and the fabric didn't move as imagined. Still, we are really happy with the final result.
