Often, we producers are encouraged to resort to third-party VST compressor plugins. There are many uses for audio compression and other dynamics processors.
A compressor can be used to even out the level of an individual track, or it can add bite, color, crunch, or creative effects to otherwise simple instruments. This is particularly true when dealing with plugins that are modeled on vintage hardware as often the coloration they add to the signal is more desirable than the compression itself.
First, a refresher. This means you might encounter new controls or discover something new about controls you are already familiar with. Threshold is simply the level at which the compressor will start to react to your audio track.
The compressor will be triggered to reduce the audio signal any time the input goes over the threshold. Turn the threshold up, and the compressor will do less work, only reacting and reducing the level of your track when the signal gets loud. If you want some gentle automated reduction on the peaks of your audio track, a high threshold is advisable.
If you want a more affected and thick sound, you might want to set it low so that the compressor works much harder. Tip: A lot of producers will recommend using two compressors in a chain, one with a high threshold to capture the peaks, then another with a lower threshold to add overall level consistency, sustain, or body to the audio layer.
The ratio is the amount by which the level will be reduced when your input signal exceeds the threshold. A high ratio understandably means more compression. The ratio is expressed as a proportion of the input level to the output level.
So a setting of means that a signal that is two decibels over the threshold will be reduced by one decibel, and a signal that is eight decibels over will be reduced by four. Makeup is a handy gain control that lets you bring up the overall level of the compressed signal. Ideally, the makeup gain should match the gain reduction so that when the effect is bypassed the maximum signal level stays the same.
The compressed signal will sound louder but should be using the same amount of headroom. Next, Knee is how harsh or gentle the compressor acts on the input signal.
In a broad sense, it changes how the compressor reacts as the signal approaches the threshold. Generally, this is quite hard to hear. Really it has a subtle effect on the overall character of the compression.
So play with this and trust your ears. Whatever sounds good for your track is the best setting. Attack is an essential parameter to get in and play with, as it controls the length of time before the compressor acts and reduces the level of the input signal.
If we squash the transients with the rest of the sound, we lose punch and impact. Likewise, Release is the amount of time it takes for the compressor to ease off and stop working each time it hits. To save you the trouble, you can use the Auto release mode, which is a reliable way of ensuring that compression is being safely applied. And then of course there are the Mode buttons up top, which change how Compressor processes incoming audio by emulating different classic hardware units. Did you know that the team at Apple spent some serious energy on giving you a great range of compressors in one package with Logic Pro X?
Not only that, but these different compressors each have a unique real-world counterpart that has been painstakingly recreated. Named after an earlier release of Logic Logic Platinum , circa ! Producers tend to use Platinum Digital when they need to make some technical adjustments to the way the level, the attack, or the release of a sound behave.
Tip: Studio VCA comes into its own on an instrument or vocal layer when you push the Threshold down and choose one of the Distortion options. Have a play, and enjoy the warm flavor of this compressor. Based on its real-world counterpart, the UREI the Studio FET Field-effect Transistor compressor is designed to give you a responsive and punchy attack, as well as providing a bit of nice color to the overall sound.
Tip: Give your lead part a solid attack to help find its place in the mix. The attack will poke through your mix and allow you to nestle the layer deeper in with the rest of the instruments, just biting through every time the compressor is initially activated. The simplest of them all, the Classic VCA is modeled on the sound and controls of the real-world dbx Notice there are no attack and release controls here.
The simplicity will help you make quick decisions, as you set the threshold and ratio to find the sweet spot. Side Note: The boffins over at Universal Audio have also released an emulation of the dbx You may want to compare it with the stock Logic Pro X plugin. Once again, they are designed with real-world counterparts in mind. If you want to get a very smooth compression effect, while still coloring the sound with warmth and richness, Vintage Opto is the way to go.
Try Vintage Opto when you want to let mid and low frequencies sing through, while higher frequencies are more finely attenuated. Fun Fact: Optical compressors literally react to a light flashing in response to the audio signal coming in. They have a bit of a sluggish response once all the conversions are factored in, resulting in their distinctly smooth vintage tone. The bad news is that a compressor will almost never fix a weak sound. Compression is intended to either bring out the best in your sounds, eliminate inconsistencies, or provide a tool for experimentation.
The good news is that Logic Pro X comes with a very solid and convincing range of compressors with a wide variety of uses. As always, have a play around, trust your ears, and enjoy your music making!
This is so amazing!.. I wish I could write these notes down on each compressors so I can pick the right one for each use case! Your email address will not be published. Interviews See All.
