Phaser effect
Similar to flanging, phasing shifts the phase of an audio signal and recombines it with the original, creating psychedelic
effects first popularized by musicians of the 1960s. But unlike the Flanger effect, which uses variable delays, the
Modulation
> Phaser effect sweeps a series of phase-shifting filters to and from an upper frequency. Phasing can
dramatically alter the stereo image, creating unearthly sounds.
Stages Specifies the number of phase-shifting filters. A higher setting produces denser phasing effects.
Intensity Determines the amount of phase-shifting applied to the signal.
Depth Determines how far the filters travel below the upper frequency. Larger settings produce a wider tremolo effect;
100% sweeps from the upper frequency to zero Hz.
Mod Rate Modulation rate controls how fast the filters travel to and from the upper frequency. Specify a value in Hz
(cycles per second).
Phase Diff Determines the phase difference between stereo channels. Positive values start phase shifts in the left
channel, negative values in the right. The maximum values of +180 and -180 degrees produce a complete difference
and are sonically identical.
Upper Freq Sets the upper-most frequency from which the filters sweep. To produce the most dramatic results, select
a frequency near the middle of the selected audio’s range.
Feedback Feeds a percentage of the phaser output back to the input, intensifying the effect. Negative values invert
phase before feeding audio back.
Mix Controls the ratio of original to processed audio.
Output Gain Adjusts the output level after processing.

Noise reduction / restoration effects
Techniques for restoring audio
You can fix a wide array of audio problems by combining two powerful features. First, use Spectral Display to visually
identify and select ranges of noise or individual artifacts. (See
“Select spectral ranges” on page 39 and “Select artifacts
and repair them automatically” on page 40.) Then, use either Diagnostic or Noise Reduction effects to fix problems
like the following:
• Crackle from wireless microphones or old vinyl records. (See “Automatic Click Remover effect” on page 90.)
• Background noise like wind rumble, tape hiss, or power-line hum. (See “Adaptive Noise Reduction effect” on
page 90 and “DeHummer effect” on page 91.)
• Phase cancellation from poorly placed stereo microphones or misaligned tape machines. (See “Automatic Phase
Correction effect” on page 91.)
