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 Flanger effect lets you create
a similar result by slightly delaying and phasing a signal at specific
or random intervals.
- LFO Type
- Specifies the wave type for the Low Frequency Oscillator:
Sin(e), Rect(angle), or Tri(angle).
- Rate
- Specifies the speed of the Low Frequency Oscillator.
- Depth
- Determines the gain level of the modulation waveform, thus
controlling the depth of the effect.
- Mix
- Adjusts the mix of original (Dry) and flanged (Wet) signal.
You need some of both signals to achieve the characteristic 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 one coming from a bad tape player.
- 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.
- Delay
- 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.
