The Fraunhofer LC3 for Bluetooth source code is now listed by Bluetooth SIG under its qualified and tested components. This means products that include the technology do not have to undergo additional codec tests.
Fraunhofer IIS is happy to announce that the Fraunhofer LC3 for Bluetooth source code has passed the official qualification process set forth by the Bluetooth Special Interest Group (SIG) and is now listed under the qualified and tested components. LC3 (Low Complexity Communication Codec) is the audio codec for Bluetooth LE Audio. The new audio architecture will enhance the performance of Bluetooth audio products in the future – both for voice calls and for media playback including music. The qualification helps manufacturers of Bluetooth LE Audio profile-based products avoid additional codec tests required for Bluetooth SIG end product qualification.
The LC3 codec was jointly developed by Fraunhofer IIS and Ericsson and provides high voice and audio quality even at low bit rates, thus overcoming major shortcomings of today’s wireless communication platforms. Compared to its predecessor, the SBC codec, it reduces the required bit rate by about 50 percent, enabling energy-saving audio services. This prolongs the battery life of products and allows devices to be smaller. The codec’s complexity meets the requirements of wireless communication platforms, and it operates at low latency and with reasonable memory requirements. Thanks to LC3’s flexible codec design, applications are not limited to voice and standard wireless music streaming services but can be extended to high-resolution music streaming by implementing the LC3plus superset.
Fraunhofer IIS is very pleased to announce that the Fraunhofer LC3 for Bluetooth source code has passed all qualification procedures and is now listed under the qualified and tested Bluetooth components (Declaration ID D056040, QDID 167204). The qualification tests have been carried out and passed for all flavors of the LC3BT source code, including fixed-point, floating-point and DSP-optimized (e.g., for ARM or Cadence HiFi). Qualification/conformance results are available on request.
Additional information regarding code features, platform availability and code integration is available in the Reference Integration Notes – download available for Bluetooth SIG members (both associate and adopter).
