RadioKit Electron (beta)

Electron takes the latest achievements in Audio over IP, to bring you ultimate tool for broadcasting, so you leave behind all of yours expensive hardware codecs.

Finally the revolution is done - you can now really exchange your outside broadcasting setup for a good smartphone, tablet, or a laptop and manage all of your transmissions through a web-browser.

And forget about Shoutcast/Icecast connotations, as this technology has nothing to do with it.

For all the geeks & nerds, here is tasty techtalk:

- The near-to-zero latency combined with website control allows to take
live broadcasting to a new era.

- Built upon Erlang - the language for building cellural networks.
Using Real Time Protocol and Real Time Streaming Protocol over UDP
- no more unreliable TCP connections and shoutcast streams.

- User interface based on React.JS - technology created by facebook,
made for the best comfort of snappy, collaborational communication.

- No hardware needed - everything is a software. Moreover: software
that's easy to integrate thanks to open web & mobile-ready APIs.

- Relies on well-tested cloud technologies and infrastructure: Amazon,
Azure & Digital Ocean clouds & the biggest European datacenter: OVH.

- State-of-the art Opus 1.1 codec that brings better quality than HE-AAC+1
with ultra low-latency and packet loss concaelment.

Supported operating systems & architectures:

Android 4.1 or newer
Windows XP or newer
Mac OS X 10.10 or newer, 64-bit (coming soon)
Ubuntu Linux 14.04 LTS, 64-bit (coming soon)

Networking:

Client-server architecture
No servers required by default (servers are hosted by RadioKit in the cloud)
No network setup required by default
