Seeing São Paulo With WSDG
PAULO —For almost 20 years, Mix106.3 FM Radio has
built a strong following among Brazil’s prized 15–29-year-old
listener demographic. The station’s high-powered top 40 signal is
heard throughout the country. As our listening audience and
advertising client base expand, so, too, do our staff and studio
windows can be seen here fully installed.
2006, the station moved to the 22nd floor of a state-of-the-art
skyscraper in São Paulo. The building’s antenna soars 1,033 meters
(almost 4,000 feet) above sea level, providing a strong signal that
reaches more than 2 million listeners a month, making that signal the
leader in 74 markets, according to the Brazilian Institute of Public
Opinion and Statistics (IBOPE).
search for an architect/acoustician led us to the Belo Horizonte,
Brazil, office of the Walters-Storyk Design Group. A 40-year-old,
multinational studio design firm, WSDG has created thousands of
broadcast, TV production and recording studios around the world.
Brazil-based partner Renato Cipriano made numerous site visits and
participated in meetings with our on-air, engineering and management
teams to help develop a studio design program to optimize the space.
One of our major concerns was that our new studios be able to take
advantage of the extraordinary 360-degree cityscape views available
from many of our windows.
The studio comprises 15 individual components. A spacious
2,000-square-foot reception room/lobby leads to a 5-foot wide,
40-foot-long corridor, which provides access to six studios, three
production suites and related support spaces, all of which border the
studio on the left is On-Air SP 1, our 200-square-foot primary on-air
broadcast suite. Directly adjacent is our 150-square-foot On-Air
Satellite Broadcast Studio. A 130-square-foot reserve studio for
future expansion resides between the Satellite studio and Production
3, which features a spacious isolation booth designed to accommodate
both voiceover artists and live performances. The right side of the
corridor is headed by Production Suites 1 and 2, a 350-square-foot
complex with two individual studios and two ISO booths, accessible by
a four-door sound lock. There are also a 100-square-foot production
lab and a 150-square-foot CMR on the premises.
every one of our studios and production suites is distinguished by
breathtaking window views. The idea of masking those views with
sound-muffling curtains was unacceptable, so we asked WSDG to devise
an acoustically and aesthetically pleasing solution.
recommended outfitting the five oversized windows in our two primary
on-air studios with Quadratic Residue Diffusers (QRDs). Custom-made
of clear glass, and fabricated in Brazil, these units were designed
to cover each window completely. QRDs consist of a linked series of
narrow, translucent “wells,” precisely calculated to diffuse the
frequency range of each studio and joined together as a single
“windowsill-to-window-top” installation. While similar units have
been used in high-end recording studios such as New York’s Jungle
City, they had never before been applied to a radio station.
These units have proven themselves extremely effective in keeping
extraneous noise from leaking into our studios from outside
(including plane and helicopter engines), while permitting a
virtually unobstructed view of the city.
