Melanson’s innovations have also been the catalyst to many
products that led to rapid product advancements in personal
computing, semiconductors and networking. His first patent in 1974
helped make modern keyboards possible, and his underlying work in
light-emitting diodes electronics helped enable LEDs to overtake
incandescent lighting in popularity by solving the challenges
around dimming. As a founding member of AudioLogic (later acquired
by Cirrus Logic), Melanson pioneered the first use of low-power
digital signal processors (DSPs) for hearing aids. He also helped
develop the first network distributed audio system, a technology
that eventually found its way into the audio wiring for the U.S.
Senate and thousands of installations globally, such as theme parks
and concert venues.
As a pioneer in professional and consumer audio equipment, he
received an Oscar® award from the Academy of Motion Picture Arts
and Sciences in 2004 for his ground-breaking contributions to the
evolution of digital audio editing for motion picture
post-production. He also developed the first 500-watt Class D
amplifier for professional audio applications, and his work in
algorithm development and implementation contributed to the active
noise cancellation found in many smartphones and laptops today.
Melanson’s career includes nearly 30 years at Cirrus Logic,
where he has helped to harness computing/processing power and
energy-saving techniques for today’s personal mobile devices and
advanced professional and mobile audio. His 500th issued U.S.
patent entitled “Driver Circuitry and Operation” was granted on
June 21, 2022. In addition, Melanson has 68 pending U.S. patent
applications.
“Working at Cirrus Logic has given me the ideal backdrop for
creativity and invention,” said Melanson. “The power reduction
invention for hearing aids, which I worked on in the 1990s, shows
up in every Cirrus Logic product we make or at least some
great-great-grandchild of it does. I love that I’m able to get
involved in technology at a deep level and work on cool stuff while
mentoring people at Cirrus Logic to keep the company’s innovative
spirit going.”
