The Base Frequency slider controls a low pass filter which selects the frequencies of the original sound that will be processed by the Phaser algorithm. Higher settings will leave lower frequency components of the sound relatively un-effected. Settings range from 0 to 10,000 Hz. The Feedback slider introduces regeneration, where the output of the Phaser is mixed back at it's input. Parameters Frequency Speed of the Flanger time-delay modulation, from 0 to 2,000 Hz.
Low settings give lush evolving flanges.
Depth Depth, in number of samples. Higher settings result in a more pronounced Flanging effect. Maximum depth is 1024 samples. The Feedback slider introduces regeneration, where the output of the Flanger is mixed back at it's input. A chorus effect can be heard whenever several voices sing the same note in unison.
