The “Golden Trace”: Your Show-Time Insurance
Before the doors open and the room fills with people, you need a Reference Snapshot. This is the “Golden Trace”—the sound of the empty room when the system is perfectly tuned.
Why do this?
When the show starts, the humidity changes, the crowd absorbs the high frequencies, and the temperature rises. By keeping your “Golden Trace” visible as a “Ghost” in the background of Smaart, you can see exactly how the environment is degrading your sound.
If you see the live trace dropping by $3\text{dB}$ above $5\text{kHz}$ compared to your Golden Trace, you know exactly how much “Air” EQ to add back into the system to maintain the afternoon’s clarity.
Hotkey: Press [Spacebar] to capture a trace instantly. Rename it “GOLDEN_EMPTY” and keep it on the screen all night.
