AB  - A White Paper for in-car measurements version 1.0 was officially published in 2023 by the Automotive Audio section of the AES. It comprises basic characteristics of car audio systems. One of the intentions was to make audio systems and different cars comparable. This paper is divided into two parts: In the first part, measurements of seven cars with different sizes, ages, and audio performance are presented based on version 1. The feasibility of the suggested procedure is evaluated, and improvements are suggested. The first version addresses frequency response, average level, and impulsive distortion at different levels. In a second part, extended data analysis and additional measurements are suggested to improve diagnostic capabilities and address non-linear distortion. The suitability of different distortion measurements is discussed and demonstrated. Time-variant effects, which are typical for DSP-based algorithms, such as limiters, protection systems, and adaptive control, are also investigated. High-level operation of transducers shows similar effects. Stationary behavior is not ensured in such systems; thus, methods to cope with time-variant effects are required.
