Phaser built from scratch using brick-wall filtering
A variation on the "phaser theme", this one is built using a time-varying low-(high)-pass filter (the Controllable Brick Wall 1
block). The Control Input is the instantaneous edge frequency of the filter, which, in this example, is driven by the
Exponential Sweep Control Generator which generates a control signal (in Hz) which sweeps exponentially in time across a
desired frequency range.
You can experiment with different types of sweep signal for both the filter edge frequency (The exponential sweep
demonstrated here just happens to be a common phaser implementation).
Try changing all parameter settings of all components to achieve a wide range of interesting phasing effects.
