A random noise generator is pretty handy when working with music, and building one using a micro-controller can be pretty trivial. So it’s nice when someone comes along and builds it from a few analog ...

A white-noise source can be constructed based on the random noise of a Zener diode or reverse-biased base-emitter junction. While these circuits work, they are temperature sensitive and not ...

A chaotic drone of meaningless sound to lull the human brain out of its usual drive to latch on to patterns can at times be a welcome thing. A nonsense background din — like an old television tuned to ...

The behavior of analog circuits can often be characterized by sweeping their inputs with a signal going across a range of frequencies and then observing the output. These sweeps can be composed of ...

The matte-black circuit board that holds Tristan Perich’s Noise Patterns has a few things in common with your average smartphone. It’s small and sleek enough to fit into your pocket, and it comes with ...
