Gain Staging
The practice of setting appropriate levels at every stage of the signal chain so nothing clips or chokes the next process.
Gain staging is the unglamorous but foundational skill of getting the level right at every step. Mic preamps, channel strips, plugin inputs, busses, the master — each has an ideal operating range, and each one is a chance to either preserve dynamics or crush them. Recording too hot into a 24-bit converter doesn't add warmth like analog tape — it just clips. Tracking too quietly buries your signal in the noise floor.
The modern target for digital recording is peaks around -6 to -10 dBFS with averages near -18 dBFS — leaving plenty of headroom for mix processing without losing resolution. Plugin gain staging matters too: many analog-modeling compressors and EQs sound best at "analog levels" (around -18 dBFS RMS) and behave oddly when fed near-clipping signal. Watch the input meter; trim before, not after.
Healthy gain staging is invisible. A mix where every channel sits comfortably, the bus has headroom, and the master can be raised in mastering without limiting needing to do violence — that's gain staging done right. It's the difference between a mix that sounds open and a mix that sounds squeezed.
