Parametric sounds [WAV]

Hi,

Abouty a week ago I discovered that some of the CAD computers at the university I now attend have Mathematica installed.
Recently, I found out that it can "graph" a function into a sound!

Attached are a sampling of som sounds I made.

Some descriptions:

AnnoyingHum is a summation of 120, the wave looks sinusoidal with lots of noise, but it has a period 10/3, which also happens to be the file length (figure...).

PowerDown is:
Sin[1500(len -  t) + 1 + Sin[900(len  - t)]]  + Sin[2000*(len  -  t)^2]
Multiplied by parabolic amplitude. Similarly for PowerUp, only backwards.


Radio is:
Sin[2Pi (440 + 440*Sin[10t*t])t]
With decaying amplitude of the form 1/(t*t + 1)

Gallop is a rather complicated sum & product of sinusoids.

IntermittendRumble is a product of 9 sinusoids, similar to AnnoyingHum.

BombDrop is Sin[400*(len  - t  + 8)^2] multiplied by parabolic amplitude.





So, if you've got access to this, play around with the Play function.

As for me, I'm struggling to make an explosion sound. I just finished implementing perlin noise, really helps...


Enjoy!

I didnt understand what you said but the sounds were cool

I get it but I refuse to think outside of school. sounds were cool
