## NoiseGen

20-Minute Software Synth

Digital sound isn't really much more than a stream of floating point numbers from -1..1 sent to the sound card at a constant rate. So... let's use that concept to generate some noise using simple programming. Here I'm using 'unit generators', built in high-level dynamic programming languages, to make my speakers jump around a bit.

# Alien Death Ray Sound?

my $lfo = sine( freq => 5 ); my$vfreq = sub {
$lfo->() * 100 + 440 } play( gen => sine( freq =>$vfreq )
)
