AutoCAD Audio

So I'm sure someone who knows more about sound than me will tell me that either a) this is a completely rediculous idea or b) they thought of this 15 years ago... but until then I want to believe that I've stumbled upon something mildly brilliant.

Today in Sound 1 we were going over sampling and bit rates, and how they're basically the x and the y, respectively, of a plotted line graph of a waveform. Having gone over this before my mind drifted to the work I have left for my AutoCAD class. At a certain point I was thinking about a 3D extrusion path I have yet to draw and the spline I would have to make for it.

It was at this moment that I realized the way we currently capture digital audio is no longer efficient. Imagine a spline in AutoCAD, the spline is constucted by certain specific points and a "curve of best fit" between them. So-- what if instead of a matrix of positional values (x,y) to replicate a sound wave we use vectors instead? Gone would be hard, articifial caps on frequency response as well as the course jumps between values because now a true unbroken linear waveform has been created based on a mathmatical model. Better still, we can enhance the model based on decades of work in calculus, which for those of you (ok, all of you) who aren't as dorky as me is the study of the rates of change of curves.

Okay, let the flamming begin. In a related story, the "J.Read is a huge nerd" t-shirts go on sale soon.
