Attack (in ms): Primarily useful in Auto Speech mode, this controls the duration over
which the noise profile is detected. Ideally, the attack time should match the variability
of the unwanted noise. A low value corresponds to a faster update rate of the noise
profile and is useful for quickly varying noise; a high value corresponds to a slower
update rate and can be used for noise that’s more consistent.
Sensitivity: Higher sensitivity values exaggerate the detected noise profile; the result
is that more noise will be removed, but more of the dialog you want to keep may
beaffected.
Ratio: Controls the attack time of the signal profile relative to the attack time of the
noise profile. A faster ratio detects and preserves transients in speech more easily, but
the resulting speech profile is less accurate.
Frequency Smoothing: Smooths the resulting signal in the frequency domain to
compensate for harmonic ringing in the signal after the noise has been extracted.
Time Smoothing: A toggle button enables smoothing of the resulting signal in the time
domain as well.
Dry/Wet: A percentage control of the output mix of “dry” or original signal to “wet” or
processed signal. 0 is completely dry, 100% is completely wet.
Makeup Gain: To let you compensate for level that may be lost due to the noise
reduction operation you’re applying, this applies a pre-gain in, from -6dB to +18dB, just
before the dry/processed mix.
Phase Meter
Phase cancellation is a phenomena where the waveforms of a stereo recording (for example a
stereo recording of a music performance) go slightly out of sync with one another for whatever
reason, and begin to cancel one another out in unpredictable ways, resulting in the audio
sounding strange. This results in poor quality audio and can cause problems when you’re trying
to compress a mix to a distribution format such as AAF or MP3.
The Phase Meter plug-in is a visual meter that lets you evaluate whether or not a signal is in
phase and is meant to be applied to a bus so you may evaluate the phase of a mix and correct
whatever problems may be occurring. The position of a green dot within a horizontal meter
indicates the phase of the signal. When there’s no signal or a signal on only one half of a stereo
bus, the dot appears in the center (0). When the signal is out of phase, the dot appears all the
way to the left (–). When the signal is in phase, the dot appears all the way to the right (+).
