Compressor/Limiters

A compressor reduces the difference between the loudest
and quietest parts of a performance. It works on a threshold
system where signals exceeding the threshold are processed
and those falling below it pass through unchanged. When a
signal exceeds the threshold the compressor automatically
reduces the gain. How much gain reduction is applied
depends on the ‘compression ratio’ which on most
compressors is variable: the higher the ratio, the stronger
the compression. Very high ratios cause the compressor to
act as a limiter where the input signal is prevented from
ever exceeding the threshold.
Compressors are the most commonly used processor and
are particularly popular for maintaining constant vocal and
bass guitar levels live and in the studio. This is because, out
of all instruments, singers tend to vary their levels the most.
Compressors help to achieve the much sought-after tight,
"punchy" sound.
