Today’s invention is to have several special recordings made of many pieces of music so that they sound optimal (to a panel of hi-fi snobs) in the hushed atmosphere of a limousine.
Ideally these variants could be created using a combination of expert listening, in-car recording and software processing. The recordings for a Bentley Continental would be very different to those for a Mercedes S class, so that the internal acoustics of each car, at different speeds, would be taken into account.
There would also be specific, choosable versions for different situations -perhaps one for each different motorway driven down regularly.
In addition, here might be a driver-only version, a four-passenger version or a sitting in the back with the driver screen up, recordings. All of these would come at a high price, of course.
