In the past years Active Sound Design (ASD) has found its entrance into the automotive field as an efficient means to add some sporty sound components to vehicles with combustion engines. Nowadays, with the growing market share of hybrid and battery electric vehicles and the legal requirement to add artificial exterior sound with Acoustic Vehicle Alert Systems (AVAS), wider applications scenarios open-up. These new scenarios require new skills, processes and tools to efficiently define, generate and implement these new types of sounds. Active Sound technologies allow a stringent implementation of a Brand Sound for the Auto OEMs. This stringent implementation requires a corresponding Brand Sound approach to define this concept into various vehicle sounds. Today's applications of Active Sound Design require a flexible and comprehensive generation of different sound types for combustion and electric powertrain driven vehicles, so that the corresponding toolchain must be flexible, easy to edit, and of specific suitability for automotive applications. A major prerequisite is that the generated sounds are authentic, even though they are completely synthesized and may have a new unusual character. Several specific sound generation features are required to achieve this, and an efficient tuning to the dynamic vehicle parameters is mandatory.
