Flanger effect
Flanging is an audio effect caused by mixing a varying, short delay in roughly equal proportion to the original signal.
It was originally achieved by sending an identical audio signal to two reel-to-reel tape recorders, and then pressing
the flange of one reel to slow it down. Combining the two resulting recordings produced a phase-shifted, time-delay
effect, characteristic of psychedelic music of the 1960s and 1970s. The Modulation > Flanger effect lets you create a
similar result by slightly delaying and phasing a signal at specific or random intervals.

Flanger options
Initial Delay Time Sets the point in milliseconds at which flanging starts behind the original signal. The flanging
effect occurs by cycling over time from an initial delay setting to a second (or final) delay setting.
Final Delay Time Sets the point in milliseconds at which flanging ends behind the original signal.
Stereo Phasing Sets the left and right delays at separate values, measured in degrees. For example, 180˚ sets the
initial delay of the right channel to occur at the same time as the final delay of the left channel. You can set this option
to reverse the initial/final delay settings for the left and right channels, creating a circular, psychedelic effect.
Feedback Determines the percentage of the flanged signal that is fed back into the flanger. With no feedback, the
effect uses only the original signal. With feedback added, the effect uses a percentage of the affected signal from
before the current point of playback.
Modulation Rate Provides settings for Frequency (measured in Hz), Period (measured in seconds), and Total Cycles
(measured in cycles). Each refers to the rate at which the delay cycles between the initial delay and the final delay.
Different settings can result in widely varying effects. For example, setting Total Cycles to 0.5 causes the effect to start
with the initial delay and end with the final delay. Setting Frequency to 4 causes the flanging cycle to occur four times
per second.
Mode Provides three ways of flanging:
• Inverted Inverts the delayed signal, causing the waves to cancel out periodically instead of reinforcing the signal.
If the Original - Expanded mix settings are set at 50/50, the waves cancel out to silence whenever the delay is at zero.
• Special Effects Mixes the normal and inverted flanging effects. The delayed signal is added to the effect while the
leading signal is subtracted.
• Sinusoidal Makes the transition from initial delay to final delay and back follow a sine curve. Otherwise, the
transition is linear, and the delays from the initial setting to the final setting are at a constant rate. If Sinusoidal is
selected, the signal is at the initial and final delays more often than it is between delays.
Mix Adjusts the mix of original (Dry) and flanged (Wet) signal. You need some of both signals to achieve the charac-
teristic cancellation and reinforcement that occurs during flanging. With Original at 100%, no flanging occurs at all.
With Delayed at 100%, the result is a wavering sound, like a bad tape player.
