Dolby Voice is an audio communication technology developed by Dolby Laboratories since at least 2012.[1] This solution is aimed at improving audio quality in virtual environments such as entreprise-level videoconferencing.[2] It is implemented using commercially available hardware and/or software and uses the proprietary Dolby Voice Codec (DVC) audio codec.
Features
This technology was created to improve audio quality, compared to other similar technologies through various audio processing features:[3] while, at the same time, avoiding to cut back on bandwidth usage and network resilience, through the use of heavy compression.
- a dynamic audio leveling to focus on the human voice, and to equalize participants audio power easing listening
- a spatialization of audio to improve voice clarity and reduce fatigue by preventing speech overlapping when multiple participants are talking at the same time
- a noise reduction to limit unwanted background sounds in noisy environments
- an echo reduction to limit audio reinjection when input and output devices are placed close together
