SOUND4 IP CONNECT – a product dedicated to dynamic audio networking
The SOUND4 IP Connect PCIe Card offers customers much more than point-to-point sound streaming. It provides a variety of audio IP solutions by incorporating a unique combination of features. It takes signal processing into account, allows for synchronization and offers secure routing in the event of an IP link failure, as well as stream duplication without decoding and re-encoding. Delay is minimal, while the network architecture can be adjusted according to the new demands of the broadcasting environment.
Live local programs manageable with two clicks
SOUND4 IP CONNECT allows clients to create a live program with two clicks, to assign a group of transmitters to a particular studio and manage an IP network through the radio automation systems.
Bandwidth Repartition
Thanks to the IP Pass-Through functionality, it is possible to rebroadcast a link from a receiver without decoding and re-encoding.
This functionality is really appreciated by broadcasters who need a significant bandwidth to deliver IP to many transmitters. Audio networking can be built like a tree - upon studio departure some links will serve four or five receivers, then each receiver will rebroadcast without decoding to four or five others receivers.
Secure Links Central to our Products
The SOUND4 IP CONNECT was specifically developed with the aim of providing you with secure links and backup.
Users can set a backup link in case the main one fails. Moreover, the SOUND4 IP CONNECT is the first Audio over IP codec which manages fall-back links with dynamic data assignment. For example, a radio can use an ADSL link for the main service and an IP satellite (2-way) for backup. The main advantage of the 2-way satellite is the cost because it is usually used for a limited quantity of data transfer. At the same time, the cost is also a disadvantage if the data transfer is not achieved. With the SOUND4 IP CONNECT Fall-back link management, it is possible to start or stop sending data to the satellite when needed. The basic subscription for a 2-way satellite can cover a backup program for more than 20 hours per week.
A Built-in Pre-processor Optimizing the Codec’s Performance
As a manufacturer who specializes in sound processing, we always pay attention to levels. With the SOUND4 IP CONNECT, we have implemented a pre-processor to optimize levels and the performance of the codecs.
The SOUND4 IP CONNECT can be used in all circumstances, even in live broadcasting where levels are not always correctly controlled. Another advantage is the fact that pre-processing is by-passable for users who do not need it.
Up to 32 Links Supported
The SOUND4 IP CONNECT can handle up to 32 links, each of them being able to run a single-way or a duplex transmission. All links are dynamically re-assignable with the Link & Share protocol.

SOUND4 IP Connect PCIe Card
The SOUND4 IP Connect PCIe Card
- 100% autonomous in terms of resources - the card only requires power from the PC.
- 4 inputs - AES from 32 to 192 kHz, analog, IP and PCI (audio driver).
- Mixing of inputs and automatic safety function.
- Routing of signals for outlets.
- Relay switch for automatic by-pass.
- Digital AES/EBU synchronization input.
- DSP computing power - 4 Giga Flops (Sharc 40 bits with floating point).
- GUI and driver compatible 32 & 64 bits - Windows 7, windows 8, Windows 10, Windows Server 2008 R2, 2012, Linux (Debian).
- Multicard driver (the quantity of PCIe slots will be equal to the number of cards admissible in the same PC).
- Start-up time of the SOUND4 IP card - 15 seconds max to being on air.
- Guaranteed security - the SOUND4 card is independent from the operating system. Thus, we can monitor the operating system and force it to reboot in case of a crash without ever having a sound cut-off at the antenna.
- 100% upgradeable and fast. While updating the card, the sound is interrupted for only two seconds for Analog and AES.
Protocol, Codecs and Links Capacity
At SOUND4 we have built a solid reputation in Audio over IP, which is the reason why we use our proprietary protocol with our own IP corrections and QOS management. This choice offers stability because it is designed for actual technology and realistic line characteristics. Our protocol is based on a UDP standard.
With SOUND4 IP Connect, we provide two types of codecs:
- Linear (PCM)
- SOUND4 LD, our own proprietary low-delay codec. Adjustable from 64 to 384 kbps.
In addition to having minimum delay, our codec also works with low bandwidth (transparent at 128 kbps). The SOUND4 LD codec is not an mpeg-based codec, it does not generate artifacts with mpeg based audio sources.
In terms of delay, 50 ms for encoding/transport/decoding is an achievable goal on a good SDSL line.
A SOUND4 IP Connect can handle up to 32 links, with each Link being able to run a single-way or a duplex transmission. All links are dynamically re-assignable with the Link & Share protocol.
