Kabruzzo – Project 2: Visualizing with Leap Motion

Mon, 09 Dec 2019 05:32:19 +0000

Since I worked with sound for my first project, I decided to work with visuals for my second project using jit.gen. For the first window “ball”, a sphere is squished and stretched based on the y-coordinate of the left index finger. It squishes when your hand is lower, and stretches when your hand is higher. It is also squished in a different direction when the left hand pinches, like you are pinching the shape. In the window “worm,” the speed at which the shape moves is affected by the left hand making a fist, and the color is affected by the position of the left index finger. In the window “cross 1,” a shape is produced by taking the cross product of vectors used to make a sphere and the vector for the left palm’s velocity. In the window “cross 2,” a shape is produced by taking the cross product of vectors used to make a sphere and the vector for the left index finger’s position as a vector.

kabruzzo – Project 1 – Audio Signal Processing With Sensors

Wed, 06 Nov 2019 04:40:38 +0000

For my first individual project, I decided to work with Arduino because I really enjoyed the videos shared on Slack on interactive sound installations. I also have worked with Arduino before, and thought it was cool that you could have it output to Max. I decided to work with flex sensors because I haven’t worked with type of sensor before and thought it was interesting. I also use a potentiometer.

I used a feedback system to create an echo. One of flex sensors pitch-shifts the echo, another one sets the delay of the echo, and the last one sets the volume for the echo. There’s also a degrade that goes from a resolution of 0 bits to 10 bits, then back from 10 bits to 0 bits in a loop. The rate at which the resolution changes is set by the potentiometer.

Kabruzzo – Assignment 4: Chlorine fft

Wed, 16 Oct 2019 02:06:11 +0000

For this assignment, I decided to use the cubey-fft patches we made in class as a starting point. Instead of using jit.mo.sin to set the position, I used the amplitudes of the audio signal. I did this by making a matrix with three planes and setting the values in the pfft. I also changed the color and shape generated, and used Chlorine by Twenty One Pilots for the audio signal.

Kabruzzo – Assignment 3: Convolving Drew Gooden

Thu, 03 Oct 2019 06:14:17 +0000

For my original audio, I used the audio from a vine by Drew Gooden. This is the original audio:

My first impulse recording was taken in a hallway in Baker Hall by recording the popping a balloon. The second impulse recording was taken in the courtyard in Mudge using the same method. My first experimental impulse recording was a ringtone. For the second experimental impulse recording I reversed the original audio and added a tempo change of -25%. Here are each of the impulse recordings:

Here are the convolved signals:

Kabruzzo: Assignment 2 – Echos of a Truce

Wed, 18 Sep 2019 04:06:16 +0000

I took the song Truce by Twenty One Pilots and used a delay with feedback. The delay is 0.75s long, and each time it repeats the volume is multiplied by 0.65 and the sampling rate is lowered to 0.4Hz. The resulting effect was similar to an echo. I choose the song Truce because it’s a slower song and I thought it would sound nice with an echo.

Kabruzzo – Assignment 1: Super Saturation

Wed, 04 Sep 2019 03:44:21 +0000

My “readymade” system is the online photo editing website fotor.com. The website allows users to make basic edits to photos, such as changing the brightness, contrast, sharpness, and saturation. I decided to use the saturation tool to see how much it could alter an image.

I used a photo I took of a dog. For each iteration, I increased the saturation by 25. I continued to do this until there was no noticeable difference when I continued to increase the saturation, which occurred around iteration 50.
