Should you use compression or volume automation when you’re mixing? The answer depends; both can be used to control dynamics. However, we think of it this way:
- Compression is great for taming peaks and unruly dynamics within a track.
- Automation is great for setting overall levels and “riding” the volume of a track so it sits correctly or pops out when required.
- Super-tweaky automation is useful for taming micro-dynamics problems that compressors can’t catch.
- Compression can be used to shape the envelope of an instrument; bring out or squash the attack, increase the apparent sustain.
By choosing and using the proper tool for the job, you can manage dynamics and still maintain the life and energy in your tracks.
