Swedish audio technology maker Dirac partnered with Fujitsu to debut a new audio technology that claims to enable clearer voice in video-conferences, without needing a messy software setup, or use of discrete GPUs. This is one of Dirac's first deployments on a commercial notebook, it's makers claim that over 500 million smartphones use Dirac technology for clearer voice in phone-calls. Among the notebooks integrating Dirac technology are the Lifebook U9311 and U9311X.

At its core, Dirac is an audio DSP that works on top of your audio codec driver. It gives users three audio modes, namely Voice Mode, Music Mode, and Movie Mode. Dirac claims that the Voice Mode in particular, significantly improves the quality of speech audio in video calls. "Dirac's patented impulse and frequency response correction digitally upgrades the sound performance of laptop speakers, and creates an expanded, natural soundscape from small speakers placed adjacent to each other. Taken together, Dirac's sound technologies enable a richer sound experience from laptops - all without any expensive hardware upgrades," the company said.
