LC3 for Bluetooth LE Audio Now Available for Cadence Tensilica HiFi DSPs
January 8, 2020 | Cadence Design Systems, Inc.Estimated reading time: 2 minutes
Cadence Design Systems, Inc. (Nasdaq: CDNS) today announced that an implementation of the Low Complexity Communications Codec (LC3) that is expected to be compliant with LE Audio, the next generation of Bluetooth audio, is available now for Cadence® Tensilica® HiFi DSPs and has been delivered to a lead customer. LC3 provides higher audio quality at lower bandwidth and affords developers greater flexibility in making tradeoffs between audio quality, power consumption and other features for a more optimal user experience. Cadence licensed reference code from Fraunhofer IIS to enable availability of LC3 in conjunction with the initial LE Audio launch, allowing customers to immediately benefit from the latest enhancements including longer battery life, improved connectivity and multi-user sharing.
“Consumer demand for a wide range of Bluetooth audio-based products from headphones and TWS ear buds to portable speakers continues to explode. We are excited that our contributions to LC3 help deliver higher quality and more robust experiences,“ said Marc Gayer, head of business department in the audio and multimedia division of Fraunhofer IIS. “We worked early on in the development of the codec to ensure that LC3 would run extremely efficiently on the Cadence Tensilica HiFi Audio DSP architecture, which translates to extended battery life for consumers.”
“The fact that the LC3 codec can provide very high-quality audio even at low bitrates makes it a key feature of the upcoming LE Audio standard,” said Mark Powell, executive director of the Bluetooth Special Interest Group (SIG). “We are pleased to see member companies working on implementations of the LC3 codec optimized for various processor architectures.”
“Fraunhofer continues to prove that it is an innovative leader in the world of audio/voice codecs with its critical contributions to the new LC3 standard,” said Gerard Andrews, director of audio/voice IP marketing at Cadence. “By working closely with Fraunhofer throughout the development of this audio codec, we are able to offer a highly optimized, ultra-low power implementation on the HiFi architecture in concert with the announcement of LE Audio. This is an example of how we’re continuing to enhance our best-in-class HiFi technology to deliver performance excellence for our customers’ audio and voice implementations.”
Tensilica HiFi DSPs are the most widely licensed audio/voice/AI speech processors. Part of the broad Cadence IP portfolio, they enable SoC design excellence in support of Cadence’s Intelligent System Design™ strategy.

SMT Perspectives & Prospects: Artificial Intelligence Part 6: Data Module 1
10/07/2025 | Dr. Jennie Hwang -- Column: SMT Perspectives and ProspectsData is one of the six pillars of AI infrastructure. It is critical to the performance of artificial intelligence (AI) models. AI data, essential to both the training and inference of Generative AI models, connotes the datasets used to train, validate, and test AI models. Training data provides models with a frame of reference by establishing a baseline against which models can compare new data using pre-trained models for predictions or generating new content.
Happy’s Tech Talk #43: Engineering Statistics Training With Free Software
10/06/2025 | Happy Holden -- Column: Happy’s Tech TalkIn over 50 years as a PCB process engineer, the one skill I acquired in college that has been most beneficial is engineering statistics. Basic statistics was part of my engineering fundamentals classes, but I petitioned the dean to let me take the engineering statistics graduate course because I was creating a senior thesis for my honors focus and needed more training on Design of Experiments (DOE).

Inside Thailand’s Rising PCB Hub: Touring a Chinese Fab
09/23/2025 | Edy Yu, Editor-in-Chief, ECIOFrom industry giants to emerging forces, many electronics companies are painting a grand blueprint for the future, laying out their plans in the investment hotbed of Thailand. This was evident during THECA in Thailand, where the most frequently heard buzzwords on and off the show floor were "going global," "building factories in Thailand," and "supply chain security.” With these insights, and full of expectations and questions collected at the exhibition, my team visited First Quality Circuit Co., Ltd., a subsidiary of Sihui Fuji, located in the Amata Industrial Park in Rayong, Thailand
Global Sourcing Spotlight: Finding the Balance Between Cost and Quality
09/24/2025 | Bob Duke -- Column: Global Sourcing SpotlightIn global sourcing, pursuing lower costs often takes center stage. It’s the shiny lure that gets buyers to cast their lines into unfamiliar waters. But seasoned professionals know that in the long run, sourcing is less about price tags and more about value. The real magic—and margin—lies in finding the balance between cost and quality.
