Classic Limiting
Mode: limit
Detector Type: AVG/PEAK
Detector Source: INT
Threshold: Adjust to material
Release: Usually short, 0.05-0.5 sec
Range: Typically 60 dB (see section about “Zones”
for usage)
Output: Adjust to material, typically above 0 dB.
These are the classic limiting modes. If the detector
is in PEAK mode, you will be able to raise the total
volume more than in AVG mode, but the waveforms
will be more distorted than in AVG mode. In AVG
mode it is easier to get a more transparent limiting,
but it is also easier to get
lots of punch in a drum
track since the slower
attack time will let the
transients through. The
original manual recom-
mends the AVG position
except when you have very
transient sounds.
Level Limiting (INT, LIMIT,
AVG)
Peak Limiting (INT, LIMIT, PEAK)
Ratio = Inf:1, Automatic make-up gain during lim-
iting. Range control forced to 60 dB on hardware
unit, but active in the plug-in.
AVG
mode is good for transparent limit-
ing
, or added punch to a bass line or drum track.
PEAK
mode is good for hard limiting
, for
example adding length to a snare drum sound or to limit
fast transients.
Limiting Modes
There are two basic limiting modes: the AVG and
PEAK detection. On top of this, you can use the
built-in pre-emphasis high frequency filter (Detec-
tor Source = DS-FM) together with the internal
signal. You can also use an external side chain to
trigger the limiter (Detector Source = EXP), which
is usually called ducking. Finally, you can set the
Detector Type to gate, which will give you nega-
tive limiting.
In theory, the difference between AVG and PEAK
lies basically in the way the detector calculates the
envelope of the signal. AVG uses Linear Integration
Detection , a proprietary method that Valley Interna-
tional developed, while PEAK uses a more tradi-
tional “log-of-the-absolute-value” method.
In practice, the differences lies in the timing. AVG
is a bit slower, has a more natural sound, but can
be tricky to work with. PEAK is faster and behaves
more like a traditional limiter.
You can always toggle between the peak and avg
modes and listen to the difference.
The limiter will let the fastest
tran sients slip through,
espec ially in AVG mode. These
tran sients will be caught by
the out put clipping, and if they
are very short in duration, the
effect of the clipping will be
inaudible.
