Time Series Analysis (RATIO=∞:1)
THRESHOLD
This determines the level of input signal required to
trigger the expander.
This determines the amount of expansion.
This determines how soon the expander returns to
its normal gain once the trigger signal level exceeds
the threshold.
This determines how soon the signal is expanded
once the signal level drops below the threshold.
The value is expressed as the duration required for
the level to change by 6 dB.
This sets the expander's output signal level.
This determines how expansion is applied at the
threshold. For higher knee settings, expansion is
applied gradually as the signal falls below the spec-
ified threshold, creating a more natural sound.
