The compressors most of us use are software program plugins that occur with our DAWs, and they do a good occupation. The versatility to be in a position to set as quite a few compressors as we like, any place in the audio chain, at any time, is the form of luxury the engineers who combined most of our favorite basic tunes could only dream of.
But these easy software program compressor plugins bear no relation by any means to the hardware compressors that all those identical engineers still use in their mixing right up to the current day. These times, it’s fairly simple to mathematically outline a compressor in conditions of ratio, attack and launch instances, and so on, and construct a plugin that slavishly follows that definition.
Again in the golden age of audio, though, that was not the way matters ended up finished. Compressors have been created with electronic components – transistors, resistors, amplifiers and valves – and these elements only could not present the infinite manage and versatility that a laptop or computer can, so coming up with compressors was a good artwork, a constant process of balancing the complex demands of the hardware versus noise, headroom and price.
If you listen to a uncomplicated electronic compressor with a ratio of 1:1, the possibilities are its output will audio just the similar as what you put in, even at a substantial level. A compressor these as the classic Fairchild 670, nevertheless, uses no fewer than 20 valves. This indicates that even when it is not compressing items, its output may well well induce all varieties of charming colouration and sonic modifications that have nothing at all to do with compression.
It is ‘extras’ these as these that demonstrate why big-title engineers enjoy the seem of their high priced racks of analogue components. Having said that, an rising selection of application emulations from the likes of UA, Waves, Softube and several much more will supply terrific emulations of this hardware and are a terrific route into the planet of ‘proper’ compression, with no the extortionate price tag tags of that common gear.

What you presently have
Most modern day DAWs this kind of as Logic, Professional Instruments, Cubase and so forth will do a fantastic work of controlling dynamics. Make certain you have mastered these before splashing the funds on pricey choices, but never anticipate components character from them.
