Surround yourself in Gaudí with Dolby Surround 7.1

Gaudí Experiència 4D. DolbySurround

When we decided to create our 4D projection, we knew the sound would be key to transporting you into the magical world of Gaudí and conveying all the emotions we wanted to share. This is why we chose to work with Joan Albert Amargós and Josep Mas “Kitfluss”, as well as a symphony orchestra to compose and record our score.

However we knew that, in addition to working with excellent musicians, we also had to use the right technology to fully immerse you in what we are explaining onscreen. For you to have a truly incredible experience, we had to use truly incredible technology. And the way to do this was with the Dolby Surround 7.1 system.

And you're probably wondering, what’s 7.1 surround sound?

This format appeared in cinemas for the first time in 1992 with the film ‘Batman Returns’ and, basically, it uses many separate audio tracks to reconstruct the sound using a system of several speakers. The numbers indicate how the speakers should be set up depending on the number of audio tracks used.

The first number indicates the number of primary tracks, each routed through its own speaker. The second digit refers to the low-frequency effects (or LFE) channel, which is sent to a speaker for low-pitched sounds. So, 1.0 is mono (one channel) and 2.0 is stereo sound. Finally, .1 is the subwoofer channel (with low-pitched sounds up to approximately 100 Hz).

There is an optimal physical configuration of the speakers depending on the number of audio channels used in order to get the best possible results. For example, Dolby Surround 5.1 uses five speakers, each reproducing a specific frequency range, distributed as follows: central (mid-range sounds or voices), front left and right (all sorts of sounds except low-pitched ones), surround left and right (for sound effects). The 7.1 system adds two additional speakers, left and right rear, creating a surround experience that envelops the audience in the film.

One of the innovations of Dolby Surround 7.1 is the use of eight audio channels to create four areas of surround sound. This improves the distribution, location and definition of the sound. Thanks to these surround zones, the director has greater control over the exact location of each detail in the score, making it possible to orchestrate the sound to better coincide with the action onscreen for a more realistic effect. More defined audio also allows us to hear individual sounds clearly and expands the auditory experience without sacrificing sound quality anywhere in the room.

By using 7.1 surround sound, we have unified the visual and audio components of our projection for maximum impact. That’s why, when you’re sitting in front of our screen, you're not just a spectator but a participant in this magical voyage through the rich universe of Gaudí’s imagination.
