Simple Explanation

Copying how a piece of audio gear works so it can be recreated digitally.

Concise Technical Definition

The process of analyzing and replicating the behavior or characteristics of a physical system using different technology, often through software or digital algorithms.

Layman-Friendly Analogy

Like creating a digital twin of a famous guitar amp so you can play it without owning the real thing.

Industry Usage Summary

Common in digital audio where hardware like vintage EQs, compressors, amps, or reverbs are emulated through plugins. Used in both studio and live settings for convenience and consistency.

Engineering Shortcut

Software emulation of hardware behavior based on measured parameters.

Full Technical Explanation

Modelling is the process of analyzing a physical system—such as an equalizer, compressor, or loudspeaker—and creating a functional digital or alternative analog representation that captures its critical performance characteristics. In audio, modelling allows hardware like rare or vintage processors to be replicated virtually using digital signal processing (DSP), making them accessible in plugin form within DAWs or digital mixing systems. This involves capturing nonlinearities, frequency response, harmonic content, and dynamic behavior. Modelling may be based on measured data (black-box modelling) or physical principles (white-box modelling). It differs from simulation, which focuses more on prediction rather than emulation. Modelling is widely used in modern audio production, amp simulation, and system design.
