Topic: 1-bit music on huge scale! (musical roads)

Someone just posted this on the system-cfg forum:

"A musical road is a road, or part of a road, which when driven over causes a tactile vibration and audible rumbling transmitted through the wheels into the car body in the form of a musical tune."

an example:

it's more or less like how vinyl records work, but it looks like there are different type of musical roads. Maybe some are using different depth, so it's less 1-bit music, more like analogic recording, but I suppose it's easier to create similar depth for all the gaps, and just make the spaces between gaps to vary.

Ha, totally forgot to reply to this. I've actually experienced this kind of road before, think it was in Norway. Imo the result is not that impressive... but yeah, I guess it's mostly about the spaces between the gaps, so it's a kind of pulse frequency modulation wink So indeed, some 1-bit trickery could work.

In it's most basic form, this technique is actually getting quite common nowadays on highways, to alert drivers when they are going over the side line.
