What type of distortion occurs when two or more different signals interfere and create new frequencies?

Intermodulation distortion occurs when two or more different signals interact in a way that generates additional frequencies not present in the original signals. This phenomenon arises particularly in non-linear systems, which can alter the relationship between the interacting signals. When these various frequencies combine, they produce new frequencies that can fall outside the intended frequency range, potentially leading to unintended audible effects in audio production and other forms of signal processing.

This distortion is especially crucial in show production and audio engineering contexts, as it can impact the clarity and quality of the sound being produced. Recognizing and managing intermodulation distortion allows producers to create a cleaner soundscape without unwanted artifacts that might detract from the listeners' experience. Understanding the nature of this distortion is essential for anyone involved in audio production, as it helps in maintaining the integrity of the original sounds being worked with.
