General
Description
The limiter’s controls are presented
similarly to the compressor’s except
that there is no ratio control. The time
constant functions, although similar to
the compressor, have different ranges. In
particular the attack time can be adjusted
to be much faster than the compressor.
It should also be noted that the threshold
level is related to the output level of the
whole dynamics application (rather than
the input level), so that any increase in gain produced by the compressor and gain
make-up do not affect the calibration of the limiting target levels.
5.1 General
Limiter
Operation
There are many methods and approaches to programme limiting that are favoured
amongst users. In general however, these fall into the two main categories described
below.
The least intrusive kind of limiting is achieved with a fast attack and a relatively slow
release, adjusted to suit the general timing of the music. Very long decays, often favoured
in classical music productions, can be achieved with the Oxford limiter by using a
combination of both release and hold times. Due to the look-ahead processing, the
Oxford limiter also has a significant range of attack time that can be used without peak
level overshoot. This means that a slower and gentler limiting can be achieved during the
onset of loud passages within the programme material, without breaching maximum level,
as set by the threshold control.
