Limiter
The limiter restricts the input signal level by compressing its dynamic range above a
specified threshold. The limiter is most commonly used to prevent clipping, protecting a
system against component or speaker damage. While the limiter is closely related to the
compressor, it applies a much higher compression ratio of ∞:1 above the threshold. The
ratio is fixed and cannot be changed. Click in each field or use the sliders to change the
values.
Threshold — The input signal level above
which limiting begins (subject to attack time)
and below which compression stops (subject
to hold and release time).
Threshold level can be adjusted from – 80.0
to 0.0dB in 0.1dB increments.
Default is – 10.0dB.
Attack Time — Adjusts the time delay for
limiting to engage after the input signal level
reaches or exceeds the threshold level.
Attack time can be adjusted from 0.0 to
200.0 ms in 0.1ms increments.
Default is 2.0 ms.
Hold Time — Adjusts how long limiting
continues after the input signal drops below
the threshold and before release time begins.
Hold time can be adjusted from 0.0 to
500.0ms in 0.1 ms increments.
Default is 50.0 ms.
Release Time — Adjusts the time it takes
to return the signal to normal (unprocessed)
levels after the signal no longer exceeds the
threshold level setting. Release time begins
only after hold time is reached.
Release time can be adjusted from 10 to 1000.0 ms in 0.1 ms increments.
Default is 50.0 ms.
Soft Knee — Select the Soft Knee checkbox to smooth and soften the transition from
uncompressed to compressed output levels. There are no adjustments.
