Phasing
The first round of the project involved a Max patch, an Arduino, and a measurement microphone with an LED attached to it.  As the microphone is moved around the room, it senses changes in sound pressure level and sends them to Max. Max maps
Here we're looking at how 282Hz from my monitors interacts with my desk and later the parallel walls of my living room.
Phase cancellations across my living room, mapped with a single, red led.  
These next pictures were done with a tricolor LED. The green streaks are analogous to the absence or fading red light in the picture above - which is where there's a loss in volume. The red light in these pictures aims to represent the antinodes or
The photography has it's own challenges and it's been a while for me since I've thought about aperture and lighting and so forth. The nice thing about these photographs is that you can actually see the room as opposed to seeing a computer represent
Additionally, the current setup is so dependent on how you move the microphone around. A single trace from one wall to the next makes it easier to understand what's actually happening at first, though we're just looking at one dimension. The goal w
ROUND 2 ! Finally, I started playing with a larger color spectrum and fixed my coding so the LED faded smoothly across the spectrum. This was challenging at the time since I was controlling the LED with one signal over serial and the RGB LED has t

The following pictures were taken at a friend's loft, which has a cross-gable style roof and 6 speakers installed in the walls. The acoustics were obviously much different than in my apartment. Since I'm more or less new to the world of acoustics,
More speaker locations.

ROUND 3!   While manipulating hue with amplitude allowed for a lot of resolution in these photographs,  some  have pointed out the obvious error in using color to represent amplitude - as color is itself a representation of frequency
