What is a phaser setting?
Phaser is a modulation audio effect whereby a series of peaks and troughs are produced across the frequency spectrum of the signal's EQ. These peaks and troughs vary over time, typically controlled by an LFO (low-frequency oscillator), to create a sweeping effect known as phaser.
What type of effect is phaser?
A phaser is an electronic sound processor used to filter a signal, and it has a series of troughs in its frequency-attenutation graph. The position (in Hz) of the peaks and troughs are typically modulated by an internal low-frequency oscillator so that they vary over time, creating a sweeping effect.
How does a phaser work?
Phasers utilize a circuit called an all-pass filter to change the phase relationship among various frequencies of the copied and original signals. As the copied signal passes through the all-pass filter, certain frequencies get phase-shifted, and the output gets mixed back in with the original signal.
What is phase effects?
(1) Phase effects: the phases of waves, reflected from and transmitted through the gradient barriers, are sensitive to the gradient of refractive index profile inside the barrier.
