Audio over IP

Audio over IP (AoIP) is a technology that allows digital audio signals to be transmitted over standard IP networks such as LAN, WAN, or the internet. Instead of using dedicated audio cables, audio is converted into data packets and streamed in real time.

Audio over IP systems are widely used in:

• Shopping malls
• Hotels and hospitality venues
• Museums and theme parks
• Hospitals and schools
• Multi-site infrastructures

These environments benefit from flexible and network-based audio distribution.

ATEÏS offers a complete range of IP audio devices:

• IP paging microphones
• IP audio encoders and decoders
• IP matrices
• IP loudspeakers
• Control software

These components form a fully integrated audio distribution system.

• Unicast: one audio stream per receiver
• Multicast: one stream shared by multiple receivers

Multicast is more efficient for large installations, as it reduces network load.

Audio over IP offers several advantages:

• Use of existing IT network infrastructure
• Reduced installation costs (no dedicated audio cabling)
• High flexibility and scalability
• Centralized control and monitoring

It is a modern alternative to traditional analog audio systems.

Audio signals are:

• Captured or generated (microphones, music sources)
• Converted into digital data
• Sent over IP networks using protocols like RTP/UDP
• Decoded and played through speakers

This process enables real-time audio streaming across multiple zones.

PoE (Power over Ethernet) allows devices to:

• Receive both power and data through a single network cable
• Eliminate the need for local power supplies
• Simplify installation and reduce costs

This makes deployment faster and more flexible.

Yes, Audio over IP solutions can integrate with:

• Traditional 100V audio systems
• SIP-based telephony systems
• Third-party IP devices using standard protocols

This ensures interoperability and easy system upgrades.
