Compressor styles
Like classic analogue synthesisers, the world’s most coveted analogue compressors are capable of fetching eye-watering prices on the second-hand market. Fortunately, though, the quality of software emulations of them has improved dramatically in recent years. The reason for analogue compressors being so popular isn’t only down to their ability to control dynamic range but also the non-linearity and distortion they bring to the signals they treat. However, this is where confusion often starts. You might know the names and model numbers of the most coveted analogue compressors of all time, but did you know that they all use different approaches to dynamic range control, resulting in dramatically variable sonic results? There are four main approaches to controlling dynamics in the analogue domain. VCA or ‘voltage controlled amplifier’ compression uses peak detection to control dynamics, so that when signals exceed a chosen threshold, the volume of the peaks is reduced to flatten the ...
