Whats the difference between .NET and, say, JRE? Why so against the .NET 
framework?

of course... For some reason I pictured you generating the sounds 
through the PC speaker, recording them recombining them.

What amazes me is how the ear detects sounds. It literally works in the 
frequency domain. :)

Right.

I wonder in this case. I'll have to grab the source again and look at 
how it was done.
