2 or 3 years ago I seen a car commercial, they used DSP as a selling point.
After that year I see no mention relating to Car noise and DSP
That is why I asked I thought it may been only a one time auto builders adventure

Bose equipment really has cornered the sound market. Providing excellent audio!
