Week 13-14 | Final Project 3D Audio

Russell — Fri, 30 Apr 2010 04:24:28 +0000

My final Nature of Code project is creating the effect of 3D audio with only two speakers. The process to create the effect of 3D audio is to invert the left channel. Next, is to reduce the amplitude of the left channel and feed into the right channel. This process is done to the right channel but vice versa. Next is to add a delay to each the left and right channel. The last step is to mix the processed audio back into the original audio track. The effect is a binaural 3D sound field.

Here is a demonstration of the 3D effect – 3D Sample

Original Track – Sing, Sing, Sing

3D Effect - Sing, Sing, Sing

A sound is placed in the horizontal plane by processing the sound with recorded head-related impulse responses.

Week 12 | Final Project Proposal – 3D Audio

Russell — Tue, 06 Apr 2010 03:04:02 +0000

For my final Nature of Code project I want to continue building upon my Audio Analyzer. I would like to 3D audio using only two speakers. The process to create the effect of 3D audio is to invert the left channel. Next, is to reduce the amplitude of the left channel and feed into the right channel. This process is done to the right channel but vice versa. The effect is a binaural 3D sound field. Currently, I have never tried this process and will see if this process works.

Week 6 – Midterm Project – Rocket

This is the current progress for the Rocket, which really is just the rocket tail. I wanted to have a denser rocket tail but I began to notice a slow down in the animation when I added more particles. The rocket tail color changes over time. The tail eventually turns into a cloud just before it dies. I was trying to emulate the tail pattern of a shuttle launch. See video.

Week 5 – Midterm Proposal

Russell — Tue, 23 Feb 2010 16:47:42 +0000

For my midterm project I would like to stimulate a rocket taking off. I will be using particles for the rockets tail. I envision the rocket sitting on the launch pad waiting to takeoff. The user will then click the mouse and start the countdown. The rocket’s particles will then intensify and the rocket will takeoff.

Here is a 3D animation I made that shows what I am thinking about.

Week 3 – Oscillation

Russell — Mon, 15 Feb 2010 22:00:36 +0000

After hours of playing around I manage to create a oscillating ball that follows a figure 8 pattern. I have a larger center ball that appear to be affected by the oscillation of the smaller ball to give the movement a more natural feel. It looks like those atomic simulations.

Week 2 – Going to Need a Stronger Umbrella

Russell — Tue, 02 Feb 2010 02:40:20 +0000

For week 2 of Nature of Code, I create a meteor shower using an arrays. The program assigns random velocities, and sizes to each meteor.

Program runs and looks better if you download the application.

Meteor Shower From The Nights Sky

Week 1 – Meteor

Russell — Sun, 31 Jan 2010 23:46:27 +0000

I wanted to create the motion of a meteor coming into Earth’s atmosphere. Seeing a meteor going through the nights sky is completely random. In my sketch I tried to create a random interval of when the meteors appear.
