The samba schools are investing in technology to improve the quality of the sound on the avenue. The musicians strive for perfection, the samba in note perfect to pack the audience and judges. But how to make the music – crystal clear, recorded in a studio – don’t lose quality at the sambadrome, an open environment with thousands of people?
in all, 53 posts of sound are scattered around the avenue. And the biggest challenge is to make the entire world listen at the same time, the sound that comes out of the car ínterpretes. As the car moves, he moves away from a box. And and approach another.
engineers need to regulate the speed at which the music arrives at the boxes more distant – so there are no delays in the sound. The process is all computerized. A device in the tire of the truck, calculate how many meters he is walking and going to being made the correction automatically.
