1 Introduction

1.1 About the “Instreamer ” ﬁrmware

The “Instreamer ” ﬁrmware is designed to serve as a versatile, network-enabled analog and digital

audio-to-Ethernet converter for commercial audio distribution.

The “Instreamer ” ﬁrmware converts audio from any analog or digital device into G.711 (8 bit), PCM

(16 bit) or high-quality MP3 streams. The audio is encoded in real-time, and the generated audio

stream can be distributed, via an IP-based network or the Internet, to one or more receivers or

Shoutcast / Icecast-servers.

Barix devices running the “Instreamer ” ﬁrmware can be easily managed via a web browser

interface using PCs, web pads, PDAs or other web-enabled devices. SNMP remote monitoring

capabilities allow for building a manageable distributed audio network. With serial and Ethernet

control APIs, open IP-standards, and the standard encoding formats, the device can also be

integrated with other components, controlled by automation systems, or used with Barix

Exstreamers to create more ﬂexible, more cost-effective distributed audio systems.

The built-in serial interface allows data to be relayed to another Barix device, a PC or a server using

the “Serial Gateway” functionality of the “Instreamer ” ﬁrmware.

With an optional stick-on transmitter, additional IR-enabled devices can be remote controlled via

the network connection, enabling users to control their audio sources without being in the same

location as the device.
