RYDSEI's video: The Fast The Furious Tokyo Drift: Engine Sounds - Mazda RX-7

Enhanced Engine/Exhaust sounds of the Mazda RX-7 from the movie The Fast & The Furious: Tokyo Drift. The engine and exhaust sounds were achieved trough editing all the different sound channels within the film by muting channels that contained music, speech etc. Why is there music/vocals etc in Tokyo Drift and the rest FF sequels engine sounds?: The reason why is that the cars from the movies before Tokyo Drift have their engines sounds taken from other cars rather than their originals (most of them) Pauls Eclipse for example comes from an Honda CRX. Which is why they have to put these sounds into a seperate audio channel which makes it much easier for me to edit. Tokyo Drift cars dont have their engine sounds replaced by other cars so theres no need to make single audio channels for the engines. Another theory is to protect the music score from being ripped by others by puting engine audio channels and the music channels together.
