The 'industry standard' in this field is Head Acoustics of Germany, who sell an insanely expensive system used by many car manufacturers to 'synthesize' the sound of their products. It's not a synthesis system, and it requires recordings that can be made only if you have a anechoic room big enough and designed to accomodate a car with the engine running and the wheels on torque-controlled rollers. Absolutely insane, but they are selling it. Ciao, -- FA Laboratorio di Acustica ed Elettroacustica Parma, Italia O tu, che porte, correndo si ?
