Engine Sound

Give any car the sound it deserves. Engine Sound synthesizes a lifelike engine in real time and plays it softly under your music. It follows your speed and acceleration, so the engine swells as you pull away and settles when you cruise — without ever stopping your music or podcasts. FIVE ENGINES • Inline-4 — eager and rev-happy • V8 — deep, lumpy rumble • Rotary — smooth, high-pitched buzz • Inline-6 — silky and balanced • V10 — shrieking, race-bred wail Preview each one with a tap. FEELS CONNECTED • GPS combined with the motion sensors reacts faster than GPS alone • Virtual gearbox: hear the shifts as you accelerate • Big animated tachometer with gear, RPM and shift lights PLAYS NICE WITH YOUR AUDIO • Mixes under music, podcasts and navigation — never takes them over • Choose how loud it sits under your music and how much it swells on acceleration • Subtle and Lead modes TRY IT PARKED Test Drive mode lets you rev every engine with an on-screen throttle before you head out. All sound is generated on your iPhone. Your location never leaves the device. Please drive safely and follow local laws. Keep the volume at a level that lets you hear traffic and emergency vehicles.
