The new compact car's luxury ride - aiming at a virtually noiseless boulevard ride was engineered by isolating the front suspension and rear axle from the car.
Since these lossless data compression steps don't add noise into, or otherwise change the contents (unlike quantization), it is sometimes referred to as noiseless coding.
This method of locomotion is extremely slow, but is also almost noiseless and very hard to detect, making it the mode of choice for many species when stalking prey.
