Discord is an internet voice conference system originally designed for video game enthusiasts. It strives for low resource usage so that it can run in parallel with other software. Discord uses the Opus audio format, an open standard designed for low latency and efficient for encoding speech. This lower latency can make conversations more natural and help avoid multiple speakers talking over each other. In the Discord application, users can individually adjust the volume of each speaker. Beyond voice conferencing, Discord also supports text-based group chats and direct messages. These messages can include images, videos, and links. Most common image and video formats will play directly in the Discord application. Discord desktop clients are available for macOS, Windows, and Linux. Smartphone clients are available for iOS and Android. Users who do not wish to install additional software may also use Discord's browser-based version.
