Compression is the process of shaping the dynamics of sounds. The main
purpose of a compressor is to take up volume of certain sounds and squash the
volume of certain sounds, but in a good way, which brings life to your music. To
use the compressor more effectively you have to understand its parameters, and
remember that this is a concise guide so this knowledge can be applied to any
compressor, digital and analog.
A compressor has got three main parts: The first part will be the
Threshold your second part will be your Ratio and thirdly you're Envelope. Your
threshold determines at what level the compressor will start compressing the
audio, and remember any audio signal below the threshold level will not be
affected by the compressor it will pass through uncompressed and anything above
the threshold will get compressed.
So how much will the audio get compressed? That will be your Ratio. This
simply means, how much volume will be applied once the audio goes above the
threshold. So 4:1 means the audio will be reduced 4 times its original signal.
The higher the ratio settings the more compression will happen.
The Envelope settings will be the time it takes for the compressor to
work. It has two parameters: The attack and the release. The attack will be the
amount of time it takes for the compressor to kick in and the release is the
time it takes for the compressor to go at rest, which means no compression at
all. A shorter attack means the compressor will kick in quickly and a short
release time will disengage more quickly and this is called the pumping effect
sometimes it sound good but it might as well sound bad at other times depending
on the type of material you working on. This is why you need to compress with a
specific goal in mind.
Serial Compression is when you using two compressors on a single
channel/Track. One compressor with a fast attack and a high threshold to tame
the peaks and another with a slow attack and low threshold to reduce the dynamic
range, but you can get the same results by using one compressor, simply delete
the second one and increase the Ratio on the first one.
Parallel Compression also known as New York compression is normally used
to compress drums. It is mixing compressed and uncompressed signals to bring out
the details while preserving the peaks. If your compressor does not have a Mix
knob/Parameter you can use the compressor in a send channel.
