## What is RealEngineSim?

RealEngineSim is a simulation game that you can enjoy the real engine sound of cars and motorcycles made by the innovative engine sound synthesis technology.
RealEngineSim uses technology completed through years of research by engine sound professionals in Hamamatsu, a region known as a home to the world’s automobile and motorcycle manufacturers. Using this technology, we have created the world’s only iPhone app able to regenerate real engine sounds. 

○This app is a simulation game in which you can enjoy the speed control and the innovative engine sound of manual mission vehicles. 

○The use of a speaker gives you even more realistic and muscular sound. 
However, we would ask you to enjoy this app with an earphone or a headset when using it in public places. 
(* Please be extra careful of the volume in order not to either hurt your hearing or trouble people around you.)


◆ Available vehicles ◆
Four types: passenger cars, sports cars, sports motorcycles, and racing cars. 
You can also enjoy controlling the acceleration, braking, clutch, and shifting of manual transmission vehicles (Auto-Clutch available). 
*There are eight additional engine sounds available for in-app purchase.

◆ Pursuing realistic engine sound ◆
Precise vehicle models and innovative engine sound synthesizers were used to achieve real engine behavior and powerful engine sound that cannot be experienced through other racing games. 
Features life-like tire slippage caused by sudden acceleration and braking. 

◆ The Driving Mode ◆
There are two modes: free driving and speed tracing 
Speed tracing is a game in which the object is to drive at a specific target speed. 
Expert mode features the racing speed data from racing cards driving on famous courses from around the world, giving you the chance to experience the excitement of racing on real courses. 
* The game modes, such as the chicken race, are available for in-app purchase.

* The new technology of engine sound synthesis used in this app was developed by an engineer, who started his own business after a long time research on the sound at Yamaha Motor Co.,Ltd. (motorcycle manufacturer). The patent application is now in preparation.
