Simple Explanation

A picture that shows how sound or audio equipment behaves—like loudness or delay—using lines or curves.

Concise Technical Definition

A visual representation of measured or calculated audio data, typically showing relationships such as amplitude vs. frequency, time vs. level, or phase vs. frequency.

Layman-Friendly Analogy

Like a sound health report card—lines on the graph show how a speaker or system is performing.

Industry Usage Summary

Graphs are used in audio engineering to display data like frequency response, distortion, group delay, and more—essential for design, testing, and system tuning.

Engineering Shortcut

Visualized data: amplitude, time, phase, distortion, etc., vs. frequency or time.

Full Technical Explanation

In audio, a graph is a plotted representation of a system’s measured or simulated behavior over a specific domain. Common examples include frequency response (amplitude vs. frequency), phase response (phase vs. frequency), group delay (delay vs. frequency), impulse response (amplitude vs. time), and harmonic distortion. These graphs help audio professionals understand, analyze, and optimize performance characteristics of speakers, microphones, electronics, and rooms. Proper interpretation of graphs is critical for accurate system design and calibration.
