CHOW Phaser is an open-source phaser effect, based very loosely on the classic Shulte Compact Phasing "A". CHOW Phaser also has both a Stereo and Mono version.
CHOW Phaser Mono is designed to accept a mono signal as input and generate a stereo signal as output. Any stereo input to the plugin will first be summed to mono before applying any processing.
CHOW Phaser Stereo accepts a stereo signal and processes each channel entirely separately. To link the controls between the left and right channels, hold the SHIFT key while moving one of the knobs.
The phaser's processing is broken up into two stages: feedback and modulation. The amount of processing done by each stage can be controlled separately with the "feedback" and "modulation" knobs. Both stages share the same LFO, which is controlled by the "depth" and "frequency" parameters, as well as the "skew" knob. The "10x" parameter simply multiplies the LFO frequency by 10. The "stages" parameter controls filter stages are used in the modulation section, while "drive", "dirt", and "thrash" add various styles of nonlinear processing to the feedback stage.
