Slower release times can smooth the transition that occurs when the signal
dips below the threshold, which is especially useful for material with frequent
peaks. However, if the release is too long, compression for sections of audio
with loud signals may extend to sections of audio with lower signals.
Note: Fast release times are typically only suitable for certain types of percussion
and other instruments with very fast decays. Using fast settings on other
sources may produce undesirable results.
L/C Meter
This meter displays the amount of gain attenuation occurring in
the limiter/compressor module.
Equalizer
The UAD Neve 88RS “Formant Spectrum Equaliser” (AMS-Neve's descriptor)
is divided into four frequency bands (see Figure 50 on page 180): High Frequency
(HF), High Midrange Frequency (HMF), Low Midrange Frequency
(LMF), and Low Frequency (LF). The high and low bands can be switched into
shelving and/or High-Q modes. The two midrange bands are fully parametric.
The EQ module can be disabled altogether.
When the high frequency (HF) and/or low frequency (LF) band is in shelf
mode, the band gain affects the band frequency. As gain is increased, the
shelf frequency more closely matches the knob value. As gain is reduced however,
the low shelving frequency moves higher, and the high shelving frequency
moves lower.
With the UAD Neve 88RS EQ, the Q value and range is dependent on the
gain setting of the band. With any non-zero gain setting, the Q will be calculated
in real-time for that band. But if the band gain is zero, Q will always display
zero.
“The unique sound of AMS Neve equalisers is the result of years of research
and extensive studio experience.”
