The importance of technology in all fields of study especially music production, can never be overlooked. The mixing process is an elaborate and intense subject in its own right and there are many different tools. One of the most useful tools to be used when mixing sound is automation.
Automation refers to when an adjustment to volume, panning or a variety of FX parameters is designed to change or move throughout the duration of sections of the song in order to achieve a multitude of goals when mixing music.
Automation is a feature that many musicians, artists and amateur music makers give little attention to, especially those that are just starting off but its importance should not be overstated. Though automation may seem like a tedious mixing process to many, its impact can be significant in various different ways.
- It can be used as a manual de-esser. This technique refers to the managing and reduction of sibilance. This is usually processed via a plug in however it can also be achieved by detailed manual automation.
- This process can also be used to control the dynamics of the vocals by finely reducing and boosting the volume throughout the audio track in specific points of a particular word. This can also add feeling to the words of the vocal, which helps the listener connect emotionally with the music. It ensures every word, phrase and syllable is heard.
- It may be used to control specific parameters on all kinds of plug-ins creating many different mixing opportunities. For example, in EDM production when building up the tension of a new track, the mixer may decide to use a low pass filter or high pass filter. This automates the frequencies that are cut out or introduced, leading up to a particular moment in the audio. This point it usually referred to as the drop.
- Automation can also be used as manual compression. Many audio engineers allow the compressor plug in to do this job for them. By manually taking off the volume peaks off your instrument tracks, you can claim more control over your mix which results in a more natural compression.
- Panning can also be enhanced with some automation. By moving different instruments or sounds throughout the stereo image, you can create interesting variations that can keep the listeners interest during the song.
Audio engineers can use a few different ways to program their automation designs.
The first is to simply use a computer mouse or track pad that can manually draw the creative idea you have in mind for the specific plug in parameter within your DAW program.
The second is to use a mixing desk or any audio device with a channel fader element included. The mix engineer can then perform the automation intent in real time.
When should I be using automation?
When mixing your music, automation is a creative tool that can be used to program the sound effects you have in mind. Whether it is EQ parameters during a vocal track or changing the amount of phase in the mix on a guitar part, the limitations are completely open to interpretation.
Producing creative and interesting sounds using automation is a great way to get your music mix to stand out and keep the listener hooked on your song.
There are an abundance of automation tutorials that can be found online, which demonstrate the many more situations of use, as well as the instructions on the specific platforms you might be using to mix your tracks.
