First in a series of essays showing how my book, Living with Moore's Law: Past, Present and Future, interacts with the bleeding edge of software development at the Heidelberg Laureate Forum, where some of the biggest brains in software history try to inspire the next generation, and be inspired by it.

I got a demonstration of just how powerful Moore’s Law of Software has become at LaLa Lab, an exhibit being held in conjunction with the Heidelberg Laureate Forum.
LaLaLab is subtitled The Mathematics of Music. It demonstrated the value of Digital Signal Processor, or encoders as Texas Instruments’ competitors call the. DSPs turn analog input into digital output or vice versa. Here they’re used not just to move the music, but to graphically show what’s going underneath, and let you interact with it.
A microphone and some instruments demonstrates how this works with a Fast Fourier Transform. Speech, the input of a variety of instruments, or just playing music comes up as beautiful diagrams ,showing just how “saturation arithmetic” fills a computer with input over time. The degree to which a note is played during each bit of a second is shown as white against the black of time itself. Each channel of input is separated, showing how a DSP can pick up a variety of types of sounds separately, giving a mixer control of it.
Nearby is a demonstration of how easy it is to control music. A tablet has sensors which turn your waving hand into output, “conducting” music from Chopin or Beethoven. The hand’s movements, and the system’s response, are displayed on a screen overhead.
There’s a lot to learn here about math, about music and about outputting results on a screen so people can understand it. I asked one of the people manning the booth how you can get the software. It’s all online, downloadable. All music teachers, or math teachers, need to do is build a curricula around it, using the extensive documentation in the booklet she handed me and the tools at Imaginary.org.
