ELECTROACOUSTIC AND TAPE STUDIO TERMS
Electroacoustic technology is rich with terminology, some of which becomes quickly dated. Here we emphasize the most generic terms dealing with audio signals and the way in which they are recorded, manipulated and reproduced. The list should be thought of as more representative than comprehensive, with emphasis placed on the original meaning of the term in analog technology with comments on how the practical aspect has changed with digital technology.
