The SOUND4 STREAM x8 also features the “Predictive HQSound” algorithm which optimizes codec results and reduces compression-induced sound artifacts.
Advanced Coding Solutions
In terms of encoding, the SOUND4 STREAM x8 offers a complete and innovative solution.
The SOUND4 STREAM x8 has a high quality encoding engine that suits every IP audio device profile. Indeed, it is the first processor that includes a sound optimizer for very low encoding rates (16 kbps, 24 kbps, 32kbps).
Another clever bit of SOUND4 STREAM x8 innovation is the adaptive processing which can correct each stream independently in order to compensate for the sound difference due to encoding. Thus, a radio station can easily generate different streams that suit the targeted audience, low-rate for mobile phones, high-rate for home devices, with homogeneous sound whatever the encoder used.
Finally, the SOUND4 STREAM x8 adapts to most of the standards used for streaming delivery systems - Flash, Darwin, Helix, Wowza, Icecast 2, Shoutcast v1 & v2, etc.
SOUND4 STREAM x8 and the Livewire standard
Livewire* is the popular IP-Audio networking standard which uses Ethernet to provide an easy way of routing and sharing audio and logic throughout the broadcast plant.
"Everyone agrees that IP-Audio is the future. There are already more than 1,500 studios around the world powered by Axia Livewire networks," says Axia Vice-President Marty Sacks. With the Livewire* system, a single Ethernet cable carries in real time all mics, as well as uncompressed digital audio, device control messages, program-associated data and even routine network traffic. One of the advantages of the SOUND4 VOICE ULA is its capacity to work as a resource that can be routed and inserted anywhere in the Livewire* chain.
Advanced Metadata Management
In terms of Metadata, the SOUND4 STREAM x8 is compatible with different standard formats and can interface with many types of automation software thanks to an XML-based gateway (A2I, BE, BSI, Enco, Jazler, Netia, NextGen, RCS, Winmedia).

User-friendly Control Interface
Through the years, SOUND4 has come to be associated not only with the quality of our products, but also with their user-friendly interfaces. The SOUND4 VOICE ULA is part of this long tradition, with a number of assets to allow users easy access, setting and operability.
Preset Sharing
Thanks to Preset sharing, it is possible to share presets between cards. This is a real advantage for operators who will use a large number of cards, as their own preset will be accessible from all channels.
Practically there is no limitation for the Preset Sharing functionality, even if cards are not in the same network map. Preset Sharing uses UDP protocol.
