Barix InstreamerNetwork AudioEncoder

Barix Instreamer - Network Audio Encoder

The Barix Instreamer is a high-quality network audio encoder that converts analog audio sources into configurable digital formats (MP3, PCM, G.711, G.722) and streams them in real time via TCP, UDP, Shoutcast, or Multicast RTP. Ideal for broadcast, surveillance, and VoIP applications, it offers reliable and low-latency Audio over IP encoding.

Key Features

• Supports G.711, G.722, PCM linear encoding
• Low latency MP3 encoding
• Shoutcast/Icecast source capability
• Audio level supervision with SNMP trap generation
• IP streaming via TCP, UDP, RTP, Multicast
• Stereo line level input (RCA connectors)
• RS-232 serial port for control and metadata input
• Powered via micro USB with included external power adaptor

Applications

• Live IP audio encoder for streaming applications
• Source encoder for IP audio distribution
• Background music and music-on-hold encoder for VoIP
