1. Warning: The Next Sound You Hear
May Not Be Your Engine
When you pay 100,000 for a red-hot BMW M5 you expect the twin-turbo
V8 to emit a mighty song. A nudge on the accelerator fills the cabin
with a richly satisfying ascent from low rumble to high scream. But
it's a digital recording, a virtual roar. A Web posting: I can't
believe it. A car that lip-syncs! BMW calls it Active Sound Design.
