Effects and transitions

Output Specifies the amount of gain to compensate for increases or reductions of frequency bands on the output gain
of the EQ.
Fill Left, Fill Right effects
The Fill Left effect duplicates the left channel information of the audio clip and places it in the right channel, discarding
the original clip’s right channel information. The Fill Right effect duplicates the right channel information and places
it in the left channel, discarding the existing left channel information. Apply to stereo audio clips only.
Think of Fill Left as “fill from the left,” and think of Fill Right as “fill from the right.”
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 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.
Highpass and Lowpass effects
The Highpass effect removes frequencies below the specified Cutoff frequency. The Lowpass effect eliminates
frequencies above the specified Cutoff frequency. The Highpass and Lowpass effects are available for 5.1, stereo, or
mono clips.
Invert (audio) effect
The Invert (audio) effect inverts the phase of all channels. This effect is available for 5.1, stereo, or mono clips.
MultibandCompressor effect
The MultibandCompressor effect is a three-band compressor with controls for each band. Use this effect instead of the
compressor in Dynamics when you need a softer sounding compressor.
