Adaptive Limiter
The Adaptive Limiter is a versatile tool for controlling the perceived loudness of sounds.
It works by rounding and smoothing peaks in the signal, producing an effect similar to
an analog amplifier being driven hard. Like an amplifier, it can slightly color the sound
of the signal. You can use the Adaptive Limiter to achieve maximum gain without
clipping (exceeding 0 dBFS).
The Adaptive Limiter is typically used in the final mix, where it may be placed after a
compressor (such as the Multipressor) and before a final gain control in order to
produce a mix of maximum loudness. Using the Adaptive Limiter can produce a
louder-sounding mix than can be achieved by simply normalizing the signal.
Note: Using the Adaptive Limiter adds latency when the Lookahead parameter is
active. In most situations, it should be used for mixing and mastering previously
recorded tracks, not when recording.
Adaptive Limiter Parameters
 Input Scale knob: Scales the input level. Scaling is useful with very high or low input
signals, to bring the level into the most effective range for the Gain knob to work
effectively. In general, it should never exceed 0 dBFS.
 Gain knob: Sets the amount of gain after input scaling.
 Out Ceiling knob: Sets the maximum output level, or ceiling, above which the signal
will not rise.
Input meters (to the left of the control dials) show the input levels in real time as the
file or project plays. The Output meters show the output levels, allowing you to see the
results of the Adaptive Limiter. The two Margin fields show the highest level for input
and output respectively (since the start of playback). You can reset the Margin fields by
clicking them.
