Simple Explanation

The process of adjusting audio or video equipment to produce more accurate performance.

Concise Technical Definition

Calibration involves using reference signals and specialized equipment to measure and adjust system parameters, such as frequency response, delay, level, or color balance, to meet performance standards.

Layman-Friendly Analogy

Like tuning a piano or balancing the tires on a car—calibration keeps everything performing at its best.

Industry Usage Summary

Used in home theater, studio, and professional AV setups to align output with design specs; done manually or automatically with tools like sound level meters, colorimeters, or room EQ systems (e.g., Audyssey).

Engineering Shortcut

Measure → Compare to target → Adjust → Repeat until optimal.

Full Technical Explanation

Calibration is the detailed adjustment of a system’s audio or visual output to match a predefined reference. In audio, this includes correcting for room acoustics, speaker delays, crossover points, and SPLs using test tones, measurement microphones, and analysis software. In video, it includes adjusting brightness, contrast, color temperature, and gamma using color calibration tools. Calibration ensures the system performs as accurately and neutrally as possible for its environment.
