"The cosmic operating system uses a command line interface. It runs on something like a teletype, with lots of noise and heat; punched-out bits flutter down into its hopper like drifting stars. The demiurge sits at his teletype, pounding out one command line after another, specifying the va...
The basic intuition is that statistics are calculated on each frequency channel to determine a noise gate. Then the gate is applied to the signal. This algorithm is based (but not completely reproducing) on the oneoutlined by Audacityfor thenoise reduction effect(Link to C++ code) ...
