LC3/LC3plus

The new LC3/LC3plus audio codec was developed in order to solve essential shortcomings present in today’s wireless communication platforms such as Bluetooth and Digital Enhanced Cordless Telecommunications (DECT). The codec’s operation modes range from medium bit rates for optimal voice transmission up to high bit rates for high-resolution music streaming services.

NESC

Fraunhofer has applied innovative AI-based technology to a new generation of voice codecs, Fraunhofer NESC, which reduces the required bitrates to some 1 kbit/s or less. Satellite and mobile operators may soon begin to offer reliable NTN audio messaging and voice services at a large scale with Fraunhofer NESC and audio quality as good as or even better than terrestrial calls.

NESC

EVS

EVS is especially designed for VoLTE (Voice over LTE) services. It enables phone calls with Full-HD Voice quality, bringing call fidelity up to the same level as today’s other digital media services.
