Presets 

 

Ultra  Light  – 

This  preset  is  similar  to  ‘LIGHT’  with  a  lower  ‘Loudness  Correction  Ratio’  and  slower 

‘Attack/Release Time’.  It provides the least amount of loudness correction available as a preset. 

 
Light  - 

This  preset  is  designed  for  very  subtle  loudness  correction  over  longer  periods  of  time.  It 

characteristically  has  a  lower  Loudness  Correction  Ratio  and  a  slower  Attack  and  Release  time.  The 
secondary Compressor is set further away from the Target as to allow more transients. The goal of this 
preset  is  to  fine-tune  long-term  loudness  levels  while  preserving  a  majority  of  the  original  signal’s 
dynamic range.   

 
Medium - 

Medium preset has higher Ratios but slower release times. This allows for full correction to 

be applied but overcomes a ‘nervous’ or ‘jumpy’ sound of fast processing. The secondary Compressor 
is set further away from the Target as to allow more transients. The goal of this preset is to achieve a 
consistent output while preserving some of the original dynamics of the input signal.   

 
Aggressive - 

The Aggressive preset has 1:1 Ratios and short Attack / Release times. The secondary 

Compressor is set close to the target to reduce transients. Frequency compensation has been turned 
off to allow equal spectral gain to be applied to the lowest of input signals. The goal of this preset is to 
achieve very consistent outputs with limited dynamic range.
