    Codec2 HF digital voice at 450 bps

    David Rowe VK5DGR reports Thomas Kurin, a student at the Friedrich-Alexander University Erlangen-Nuremberg, has developed a version of Codec2 that encodes speech at just 450 bps

    Any speech codec running as low at 450 bit/s is pretty special, and this work is also a great starting point for further innovation and quality improvements.

    Thomas has sent me some samples, and is working with me to merge his new mode into codec2-dev, and has kindly offered to tell us his story below.
