Design of the Music Visualization Project

Design of visualization

General design:

Our analysis of the music was performed in Matlab, whilst our visualizations were run using Java, with an IDE called Processing, which contains a user friendly graphics library.

A major part of our design was choosing how to map the data from our results in Matlab to our visualizations in Java. Once the mapping was chosen, we had to keep our visualizations synced with the music, and maintain a constant framerate in the visualizations. An example of our visualization without any input is shown below:

Using matlab:

We chose to get the two most dominant components from every source, giving us a total of six components per frame, and chaining them together to determine what our "notes" were. Then, we displayed them as falling rain, or lines, from the top of the screen, with their frequency determining where they appear (low frequencies to the left, high frequencies to the right), and their duration determining the length of the line that appears.

Using java:

We chose to use the FFT of the song to control the color wheel at the center of the screen. The low frequencies of the song were mapped closer to blue, whilst the higher frequencies were closer to red. The amplitude of each frequency determines the radial expansion of each line in our color wheel.

Finally, we used a process called BeatDetect, which was part of the library in Processing, to create our last animation. BeatDetect ran FFT on two (normally one) low frequency bands of the song to determine the higher amplitudes found, and calls them a beat, then, at each beat in the song it will release around 200 particles radially from the center of the color wheel.

there is no specific books for beginners but there is book called principle of nanotechnology
what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry

Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
What is lattice structure?
s. Reply
of graphene you mean?
or in general
