Fraunhofer IIS Demos Full-HD Voice Over LTE On Android

Posted by timothy on from the smell-o-vision-lite dept.

MojoKid writes "Fraunhofer IIS has chosen Mobile World Congress as the place to present the world's first Full-HD Voice mobile phone calls over an LTE network. Verizon Wireless has toyed with VoLTE (Voice over LTE) before, but this particular method enables mobile phone calls to sound as clear as talking to another person in the same room. Full-HD Voice is already established in several VoIP, video telephony and conferencing systems. However, this will mark the first time Fraunhofer's Full-HD Voice codec AAC-ELD has been integrated into a mobile communications system. Currently, the majority of phone calls are limited to the 3.5 kHz range, whereas humans are able to perceive audio signals up to 20 kHz. The Full-HD Voice codec AAC-ELD gives access to the full audible audio spectrum."

    wow this sounds really cool. I think it's so lame that as technology improved in the past 15 years and we went from landlines to cell phones, we took a huge step back in audio quality. Kind of like the step back from CDs to MP3s. I hope this catches on - do both parties need to use it? Perhaps it will be directly implemented in Skype or something.

      Skype currently uses the SILK codec, which should give similar quality.

      Skype was also involved with the IETF working group to produce a new codec (called Opus) which is also high quality and will hopefully see more widespread adoption than this AAC-ELD codec.

      Would be interested in seeing some comparisons between Opus and AAC-ELD, especially since Opus can do both voice and music due to its hybrid nature.
