RadioKit Electron (beta)

Audio over IP reloaded: replace OB van with a smartphone!

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

Built-in NAT traversal (UDP hole punching)

VPN access (coming soon on-demand)

Designed to operate with cable, WiFi and mobile (3G and newer) IP networks

Codecs:

Opus 1.1 (RFC 6716)

Packet Loss Concealment enabled

Error Correction enabled

Bitrate from 5 to 510 kbit/s

Based on OAuth2 standard

Built-in web-based authentication system

Monitoring & management:

100% web-based monitoring panel

Support multiple users operating collaboratively

Web-based peakmeter showing reference signal from the server

Ability to adjust connection parameters via web browser during transmission

Extras:
