Personally i don't like it"With the use of active systems for sound design, engineers can actively shape and optimise interior sound and thus systematically influence “heard” dynamics. In order to produce the desired sound patterns, the natural sound of the engine is intelligently refined with an electro-acoustic system. A digital signal processor interactively generates additional sound components based on constantly updated driving data so that a harmonious overall impression is formed. Initial research projects have already shown how effective that is. In a MINI prototype presented in 2009, a four-cylinder engine can be made to sound like a powerful V8 engine or superior straight-six engine."The only sound enhancing additions should be engine and drivetrain related i.e exhaust and intakes NOT an acoustic reproduction of an engine generated by dsp ... That's pretty lame ...</blockquote>
