Mettā is an OS for mobile, multimedia, and social applications. Mettā's purpose is to be easily deployable over a range of mobile and home devices, without tedious setup procedures, while allowing people to communicate easily in a very ambient way and express themselves freely by creating, modifying, and publishing text, audio, and video information in a simple way. Mettā's flexibility comes from transparent resource manipulation and transparently distributing computing tasks between nodes on the network, while maintaining data integrity and privacy.
trx is a toolset for broadcasting live audio from Linux. It sends and receives encoded audio over IP networks, via a soundcard or audio interface, and can be used for point-to-point audio links or multicast (e.g., private transmitter links or audio distribution). High-quality wideband audio (such as music) can be sent with low latency and fast recovery from dropouts.
