Audio terminology is widely explained in books, technical literature, and online resources. However, for many terms, understanding the definition alone does not necessarily make it clear how the concept can be applied to recording, playback, or acoustic design.
General explanations may also make it difficult to see what a term truly means in the context of sound production and spatial audio, or why it matters in practice.
In this glossary, Hideo Irimajiri revisits each term from a practical perspective, drawing on the knowledge and insights he has gained through many years of work in recording, broadcasting, and spatial audio research.
The terms featured here are primarily related to topics covered in the “Engineer's Note” section of this website, and new entries will be added as needed. This is therefore not intended to be a comprehensive dictionary, but rather a collection of concepts considered important in the practice and study of recording, broadcasting, and spatial audio.
