LC3plus

LC3plus is the industry-leading wireless audio codec that lets you deliver outstanding sound quality with minumum latency. The technology’s low complexity meets the requirements of wireless communication platforms such as Bluetooth, DECT, and VoIP terminals. Thanks to its extremely low delay, it is the best choice for high-end gaming headsets and audio systems and its improved robustness delivers interruption-free phone calls even under challenging conditions.

LC3plus is fully backward compatible with LC3 in Bluetooth Low Energy Audio. This makes devices with an upgrade to LC3plus work seamlessly with existing LC3 ones, letting consumers enjoy the benefits of enhanced performance without losing compatibility across their devices.

Application Fields

Gaming

In gaming, split-second decisions can make or break a victory and audio delays can leave gamers the crucial step behind. Ultra-low latency is essential to keeping audio and visuals perfectly synchronized for an unparalleled experience.

LC3plus is the ultimate game-changer for audio in gaming, the largest and most lucrative sector of the entertainment industry. It delivers ultra-low-delay modes down to 7 ms end-to-end-latency that make it the perfect choice for headset manufacturers catering to highly demanding customers, which expect a flawless performance of their high-resolution wireless and premium gaming headsets.

LC3plus is the only open-standard audio codec designed to deliver both high-quality sound and low-latency performance. Fraunhofer IIS supports businesses in its integration into devices based on the Bluetooth A2DP profile or on Bluetooth Low Energy Audio.

Home Entertainment

The perfect home entertainment setup should deliver rich and immersive sound – no matter if it comes with or without visuals. Such outstanding sound experiences traditionally relied on wired speaker systems. High-end manufacturers now use LC3 plus to revolutionize the market with wireless connections.

LC3plus helps transform living rooms into entertainment hubs. With its ability to deliver high-resolution audio, LC3plus ensures that every sound, from the quietest whisper to the most thunderous explosion, is delivered in stunning detail. LC3plus supports sample rates up to 96 kHz with an excellent THD+N performance as low as -132 dB. The codec was designed to enhance the performance of home entertainment systems, making it the perfect choice for everything from wireless soundbars to multi-channel speaker setups. Audio lag and distortion are a thing of the past with LC3plus and movie nights, music sessions, and gaming marathons will sound better than ever before.

Mobile Audio

Today, the most prevalent mode of audio consumption is mobile – from calls to TV shows and all the way to music. This means that headphones and earbuds have to deliver outstanding sound quality.

LC3plus brings top-tier audio performance to your mobile devices. Designed to deliver robust, high-quality audio even in challenging environments, LC3plus uses Advanced Packet Loss Concealment to deliver superior voice clarity and high-fidelity music streaming on the go. The Advanced Packet Loss Concealment is by default active in every LC3plus decoder and makes the codec up to three times more robust against packet losses compared to the regular LC3.

Content Creation

Content creators want to invite their audiences to shared experiences and deliver compelling messages. This requires capturing and transmitting detailed, lifelike sound and makes creation, particularly podcasts, vlogs, and live streams, depend heavily on audio quality. Creators are looking for devices that capture every nuance of their performance.

LC3plus is the ideal codec for manufacturers of professional-grade audio equipment. With low latency and high fidelity, LC3plus ensures that wireless microphones, cameras, and other recording devices deliver pristine sound that is perfectly synchronized with the video. LC3plus supports frame durations of 10 ms, 7.5 ms, 5 ms, 2.5 ms and even 1.25 ms, making it the perfect choice for low-latency applications while fitting into standard transmission intervals.
