Test drive the sounds of your dream car and enjoy the SoundRacer engine sounds. The greatest car sounds ever heard in a family car!Now you can try out the SoundRacer sounds in your smartphone. Experience some of the coolest engine sounds in the world. Test drive your dream car with your smart phone. The sounds are recorded from famous sports cars.Choose between these great engine sounds:Big American V8 muscle car - real Shelby soundExotic Italian V10 sports car - real Lamborghini soundLegendary Italian V12 sports car - real Ferrari soundThrilling Japanese V10 supercar - real Lexus LFA soundClassic American V-Twin motorcycle - real Harley soundThere are two different driving modes that you can try in the free version. Simulate the engine sound with the manual or automatic drive modes.In the paid app you now have the exciting OBD-II mode where the sound follows the engine speed in the car you are driving. You can also simulate the engine sound with the manual, automatic, paddle or tilt modes.The OBD-II app experience is as fun and exciting as driving a car with a real SoundRacer product but there are a couple of differences:One feature in the app is that you can change the ratio between the engine rpm and the sound rpm. If, for example, you are driving a low rpm diesel it can be set so that engine sound goes on 6000 rpm when the car engine is doing 2500 rpm. The sound and rpm following in the app is depending on the OBD-II adapter and phone performance and may be different than in the SoundRacer FM transmitter. The experience of the free app is naturally not as fun and exciting as driving a real car with a real SoundRacer product or the OBD-II mode but you will get a hint of it.HOW TO USE:MENU BUTTONWhen you touch the Menu button on the screen or press the Menu button on the phone, the Menu will show up at the bottom of the screen.
