What is IP Audio?

IP Audio (also known as Audio over IP or AoIP) describes technology used for the connection, conversion, coding and transmission of sound and audio via ‘IP Networks’.

Audio source entities – microphones, music players or even cloud / hosted audio content such as curated music, are routed by the network to IP speakers and other play-out entities. 

Commercial IP Audio describes how IP Audio technology and IP audio applications are used within the various commercial markets and industry sectors.

Why IP Audio?

When compared to traditional audio technology, IP Audio enables enhanced function, capability and installation topology options.

The communication audio path between IP Audio entities (eg. IP microphone and IP Speaker) is not fixed like traditional audio cabling. Removing this restriction, IP Audio system designs and installation is simplified and allows for improved scalability and flexible installation deployment.

Unrestricted from static cabling constraint, routing of audio via IP offers scalability and flexibility not available using fixed, traditional commercial 100v line audio. IP audio routing is configured via device firmware or system management software.


Example: Audio from source entities, such as an IP microphone or IP audio player, is routed flexibly without cable concern or restriction to play-out entities / speakers.

IP audio 'Zones' are created and managed through device GUI firmware and system management software. This capability provides very flexible configuration, control and adjustment of audio zones without having to alter any wiring (required using traditional audio).


Example: Structural or functional changes to a workplace (eg. an existing office work space is converted to a production area). Speakers in this workplace are simply re-configured with new audio zone details - no alteration to cabling is required.

IP audio configuration and system management is offered via two typical GUI options:

1. Device firmware: For smaller, less complex system designs.

2. System management software: Generally used for larger more complex designs.

Both options offer significant system administration improvement and capability to traditional audio, which typically has little or no configuration / system management available.

IP audio provides functionality and capability hard to achieve or simply not possible with traditional audio. 


With growing customer expectation and demand, IP audio and supporting communications & infrastructure technologies have enabled new commercial audio capability not previously available. 

  • Web & Cloud based, 'curated' music services.
  • Hosted and premise streaming audio services
  • Audio 'QR' advertisement, notices, infotainment 
  • Embedded IP audio capability through security, safety (eg.  CCTV talkback).

How does IP Audio work?

Most IP audio system designs typically employ four basic entities:

  • Audio Source (eg. microphone, music player)
  • Audio Processing (firmware & software) 
  • Audio Distribution (cabling & transmission)
  • Audio Output (Play-out devices, speakers)

Traditional audio systems, audio entities are connected ‘chain like’ by a dedicated fixed cabling infrastructure. This arrangement has stood the test of time and works well for basic commercial audio applications. However, the fixed cabling creates a rigid topology which limits capability and function for more enhanced or integrated audio system designs.

IP audio systems entities are connected to the network via ethernet cables, which in turn connect to a network switch. From that point, the audio connection path is no longer physically connected, rather logically connected from end to end (streaming IP audio). IP audio therefore offers improved scalability and flexibility for audio routing and integration with other network connected audio equipment and entities.

IP audio source entities such as an IP microphone contain an integrated IP ‘encoder’ to convert the electrical signal audio to IP audio. Once connected to the network the resulting IP packets are routed and streamed to one, many or all audio play-out / IP speakers. IP speakers contain an integrated IP ‘decoder’ and mini-amplifier to convert IP audio back to electrical audio and activate the speaker driver for audio output.

IP Audio 'Entities'

The choice of IP audio devices and product entities is primarily based on the required audio application/s. For example, product devices required for a simple IP Paging, IP PA, IP Tannoy application are likely to include IP Microphone and IP Speaker entities. Depending on the scale and complexity of the design, device firmware or dedicated software may be required to provide enhanced configuration, control and management.  


IP Audio 'Entities' and Products

For most commercial IP audio projects, products can largely be defined and grouped into category ‘entities’ as follows:

IP Speakers plug into the network for service (just like any other network device). Most IP speakers also receive power from the network switch (Power over Ethernet, PoE), in which case no additional cables or connections are required. IP speakers are essentially an IP audio decoder with a 'built-in' amplifier to provide output from the speaker itself. Different manufacturer IP speakers provide different capability - for example, some have a built-in microphone to enable 2-way audio talkback.

IP Microphones connect to the network via a standard network cable. Some IP Microphones require main power, others use Power over Ethernet (PoE). IP Microphones are operated just like regular microphones. Single zone and multi-zone IP Microphones are available. Physical button and screen-based IP Microphones are available. We also offer an IP Console solution which is GUI software based, using a PC microphone / headset for audio. 

These devices are used to 'en' code traditional electrical audio signals for interface and distribution by IP and network infrastructures. For example, a traditional CD player could be connected to an IP audio encoder which could then be used as an IP background music (IP BGM) source for streaming and play-out through single or zone groups of IP speakers.

These devices are used to 'de' code IP audio for interface and connection to traditional audio speakers and system equipment. For many new audio installation projects or to 'IP enable' existing traditional audio systems, we will often connect an IP audio decoder to an input of a traditional audio mixer/amplifier. This can be transformative in both system design / topology and capability with play-out from streaming IP audio from an IP microphone, or other IP audio source (internet radio, music streaming service or an IP audio encoder). For large project sites running traditional audio, IP audio encoder / decoders could be used to distribute audio between locations and buildings, improving and simplifying audio routing capability whilst minimising local cabling investment. 

IP audio products and devices need to be configured to enable audio function and capability. Firmware is the running configuration that resides on the IP audio device (eg. IP speaker). Software is generally separate from the IP audio devices and works with the device firmware to provide enhanced function or capability. For example, some IP audio suppliers offer software/server combination for control and management for larger and more complex IP audio system installations.

IP audio can originate from a number of source entities. This could be from a traditional CD player or radio tuner connected to an IP audio 'en' coder, an internet radio or from an internet music content provider. An IP audio Player device can be used to combine many different play-out options, including audio messages (eg. security, safety announcements). Importantly, IP audio players can also run to time schedule/s  - eg. initiating play-out of music, radio and messages to time schedules (BGM with advertisements or covid announcements would be a good example).

IP Audio Applications

Common examples of IP Audio Applications used within many different commercial and industry business sectors.

IP audio applications are not exclusive and can be combined collectively with other IP audio applications. Mixed-technology audio applications (IP & Traditional) can also be combined to create highly capable and cost effective audio design solutions.

IP PA | IP Tannoy | IP Paging

Plug in an IP speaker, plug in an IP microphone. Use your browser to configure…. Bingo, you just created a simple IP Public Address (IP PA) solution. Unshackled from dedicated cabling, with audio distribution via the LAN, WAN, VPN and Internet, IP PA can scale effortlessly. IP PA ‘gateways’ can be used to enable IP PA announcement capability from a smart phone app or from SIP IP phones.

IP Music | IP Radio | IP BGM

IP Background Music (IP BGM) leverages IP communications and IP network infrastructures. IP BGM is widely used across all commercial industry sectors to store, control, route and play-out music and radio. Legacy audio play-out devices (CD player or Radio Tuner) can be connected through an IP Audio Encoder. Dedicated IP audio music/radio players allow for simple storage and control of music libraries and playlists. Internet and cloud based streaming BGM services further elevate capability offering ‘curated’ IP BGM offering tailored play-out and branding across industry sectors.

SIP VoIP Phone Announcements

Many businesses now use SIP / VoIP to support their telephony. IP Audio devices and entities can integrate directly with on-premise or hosted IP telephony services (to enable Paging, Tannoy, PA announcements from telephones). SIP VoIP telephony gateways also exist to connect and integrate with traditional analogue audio systems.


SIP IP Telephony Audio Integration

IP Intercom

IP Intercom applications have been transformed by IP audio. Scalability and flexibility through improved installation deployment, audio routing & zoning have enabled enhanced intercom capability. Session Initiation Protocol (SIP) is a generic standard that is used by most IP telephony systems to establish and control telephone calls. Most IP intercom systems use SIP similarly, enabling integration with customer telephony / telephones. 


IP Intercom System

IP audio can be used to deliver targeted audio to security locations including CCTV points and coverage areas for 'talkback' applications. Local or remote monitoring stations can target live announcements or recorded audio messages to CCTV points individually, as groups or all points.


IP CCTV Talkback

IP audio can be used to create a scalable audio mass notification solution. Lock Down and similar security announcements can be stored and triggered by physical buttons, switches and relays an/or via secure browser GUI buttons providing improved trigger point flexibility.

Time based scheduling of audio message playback is also possible for any routine security and informational announcements.
