All about Studio Compressors and the Recording Chain

So, have you heard about or pros talking about compressors during the process recording/producing records? Of course you have. Many of the engineers in the music production scene often boast about their glowing tracks and how well they have achieved it through compression. Now to address what the pros are talking, lets look at and discuss(in comments) about the compression process, where and how to use compression in the recording chain etc.,
Compression, typically is an effect that can normalize your audio up to the levels where it stands out to sound uniform and neat. It evenly arranges the audio material and controls the levels that is very important, when there are large amount of tracks involved in modern day recordings. Thanks to all the computer power and the digital technology. Many audio professionals use compressors in all of their works and its very rarely we hear from someone who never have used compression in their music production. Well, most certainly when the mix goes to a mastering stage, it is quite obvious to use compression to polish the track and it has become a necessity to use compression in today’s world, be it analog or digital realm.
Well, there are times when compression is over used too, which is quite a human nature to overdo things
. So lets not get there.
So how are compressors used in a recording studio or even in your regular home studio ?. There are 3 places where you can use compression. They are noting but the the recording chain, tracking chain and the mix-down chain. Let’s see each one of them below..
Recording Chain
In this step, the compressor is on a direct out or an insert of the mixer, which takes the mic signal, after getting boosted by the preamp. The main focus here is to normalize/optimize the audio while recording. But there is a strong opposition among folks recording on the computer sequencers(which is what it is today), in NOT to record with compression, but to record at complete 24 bits.
Tracking Chain (Which is were I use in my recordings)
In this step, Once your audio track is recorded on computer or on a multi-track, you can now add compression to each track individually to make them all sound even and normalized. The compressor here is added as an inert on the mixer.Say in the computer sequencer’s, the compression is added as an inerst plugin.
A classic compressor such as the UA LA-2A is a great choice for vocal tracks. It helps maintain the vocals polished on top of the underlying music tracks. But not many can afford such costly hardware compressors, specially the home studio music producers. The job can still be achieved well through all the modern software compressors that do a terrific job these days. So no worries.

Mixdown Chain
In this step, a few compression techniques may be used. Compressors can be applied on the busses or even on sends/returns, to accentuate certain parts of the mix.
Another advanced mix technique is called Parallel Compression, where the uncompressed source tracks are mixed with the compressed singnal coming back on a return or bus. It is a very good technique to adapt to and you can achieve some shining results. Try it out !!!
Some tend to put compressor on the master bus. You can avoid that, as you can deal with adding compression in the master stage, whether you send to a mastering house or do it yourself. When you do it yourself, try to make a nice solid mix and then take the bounced audio for the master project, rather than mastering on the mix project itself.
So that’s some breifing on compression folks. Please do check out my other post on “Should the Vocals be Compressed while Recording”
