Compressor plugins are one of the must-have tools in your mixing arsenal. Without them, you can’t create great mixes and tracks.
Fortunately, today we have a huge number of great plugins. And the compressor is one of them. You can find many free or premium plugins that work great.
Every DAW comes with free, built-in plugins or effects. You can use them and it’s fine. But most of them lack some features and sound quality.
And because of this, I am here to find, test, and recommend some awesome compressor plugins you will love.
What Is A Compressor
A compressor is a tool for instruments or vocals. The primary usage of a compressor is during the mixing process. Sometimes during mastering. What it does is compress sound, which makes it more consistent. In general, the compressor smoothes high peaks and simultaneously brings up low frequencies.
The compressed audio is more even. Sound becomes less dynamic. So, when you use a compressor, you must be careful. Because it can ruin your mix. And there are different kinds of compressors.
On most of the compressors, you will see controls like ratio, attack, release, threshold, and gain. Sometimes there is a knee knob for smoothing the compressor effect.
You may find a simple compressor that you can use on tracks. But also there are bus compressors. These compressors are for the master track. It acts as the glue to the whole mix.
Digital vs Analog Compressors
Like many things nowadays, compressors can be digital or analog. Digital compressors are becoming more popular in this digital recording era. They are cheaper, easy to use, and require no maintenance.
For example, compressor plugins are digital. They are programmed and do what the compressor should do. Some digital compressors are based on a real, analog compressor and emulate their sound.
On the other hand, an analog compressor is an actual device. It has inputs, outputs, and all the controls you need. Also, it’s called an outboard compressor. You have to install it on the rack and connect it to your computer and DAW.
In general, analog compressors have a more natural sound. They affect the sound in a good way and add flavor to it. And digital compressors are cleaner. What sounds go in, the same, unaffected sound comes out.
But many digital compressors emulate famous analog compressor sounds. So, if you love old, analog sounds, you can always use them.
