Rob Hordijk Phaser Filter: Difference between revisions

 

Both phaser and filter can sweep over a range of roughly 18 octaves and can be modulated up to really high audio rates. In this last case FM-type and ring-modulator-type effects occur, but with much more timbral control than traditional ring-modulators. E.g. when the outputs of two OSC HRM modules, set to sinewave output and tuned in some interval, are mixed and routed into the filter just slight amounts of the internal modulation on either the phaser or the filter will start to produce ‘undertones’ and ‘overtones’ that are sum and difference frequencies of the interval. This exemplifies the idea behind the Phaser Filter architecture, to not only take material away like a normal filter does but to also produce new material not present in the input signal and combine the both to create a vast range of possible timbres.
