Adds a phaser audio effect to an audio bus. Creates several notch and peak filters that sweep across the spectrum.
A "phaser" effect creates a copy of the original audio that phase-rotates differently across the entire frequency spectrum, with the use of a series of all-pass filter stages (6 in this effect). This copy modulates with a low-frequency oscillator and combines with the original audio, resulting in peaks and troughs that sweep across the spectrum. This effect can be used to create a "glassy" or "bubbly" sound.

- Intensity of the effect. Value can range from 0.1 to 4.0.
- The volume ratio of the filtered audio that is fed back to the all-pass filters. The higher the value, the sharper and louder the peak filters created by the effect. Value can range from 0.1 to 0.9.
- Determines the maximum frequency affected by the low-frequency oscillator modulations, in Hz. Value can range from 10 to 10000.
- Determines the minimum frequency affected by the low-frequency oscillator modulations, in Hz. Value can range from 10 to 10000.
- Adjusts the rate in Hz at which the effect sweeps up and down across the frequency range. Value can range from 0.01 to 20.
