SOUND 4 STREAM X 4 PCIe FOUR CHANNELS STREAMING WEBRADIO PROCESSOR 11002+34002 INCLUDING STREAMING LICENSE

STREAM x4 is characterized by sophisticated 3-band processing, where a single S.I.S. (Sound Impact System) algorithm guarantees the gain in each of the bands to ensure complete sound stability. "Coloring" is controlled by the Fidelity parameter, thanks to which sound texture can be either "purist" or "colored". The Automatic Gain Control operates in broad band and its main purpose is to reduce gaps in levels applied to the processor, while the Tone FX feature combines a 4-band parametric Equalizer and an effect system that makes it possible to strengthen both high and low frequencies. STREAM x4 has a 100% mono-compatible stereo enhancer and a Brick Wall Limiter providing solid gain limitation. Another important feature of this product is the sound optimizer for very low encoding rates (16 kbps, 24 kbps, 32kbps). The adaptive processing 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 or high-rate for home devices.

SOUND4 STREAM x4 is compatible with most of the standards used for streaming delivery systems - Flash, Darwin, Helix, Wowza, Icecast 2, Shoutcast v1 & v2, etc. In addition to that, its ability to operate with many types of automation software allows for advanced metadata management. Setup and control is aslo very easy thanks to the software interface.

SOUND4 STREAM x4 - The First Solution of its Kind

SOUND4 is delighted to bring to the attention of our customers a solution the likes of which have so far never been introduced to the broadcasting market. The SOUND4 STREAM x4 is the very first multi-channel processor dedicated to WebRadio bouquets. It has the capability of simultaneously and independently processing a total of eight radio streams on a single PCI express card.

The SOUND4 STREAM x4 offers 8 inputs and 8 outputs through Audio Driver (WDM/Direct Sound) and/or AES67/Livewire. The streaming engine can provide 6 streams per channel for an unparalleled total of 48 streams. Each stream is set on the latest codecs generation (AAC, HE-AAC, HEAACv2 , as well as MP3).

A True Processing Chain

Created to offer clients only the best, the SOUND4 STREAM x4 includes a true sound processing chain dedicated to webstreaming:

• AGC
• Tone FX
• Stereo FX
• 3-Band Process
• 4-Band Limiter
• Brickwall Limiter

The SOUND4 STREAM x4 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 x4 offers a complete and innovative solution.

The SOUND4 STREAM x4 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 x4 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 x4 adapts to most of the standards used for streaming delivery systems - Flash, Darwin, Helix, Wowza, Icecast 2, Shoutcast v1 & v2, etc. 

SOUND4 STREAM x4 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.
