SOUND4 STREAM x4 is a high-end Webradio Processing & Encoding product which allows for the simultaneous and independent processing of four radio streams on a single PCI express card. The streaming engine can provide 6 streams per channel for an impressive total of 24 streams, with each stream using the latest codecs generation (AAC, HE-AAC, HE-AAC v.2, as well as MP3).
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:
- 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.
Advanced Metadata Management
In terms of Metadata, the SOUND4 STREAM x4 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.
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.
Wide Band AGC
One of the main processing functions of the SOUND4 STREAM x4 is the Wide Band AGC - automatic gain control, operating in broad band. Its main purpose is to “even out” gaps of levels in terms of processing.
The algorithm which was especially developed for this AGC is of the predictive type. It allows very high sound variations without any sort of pumping. Compared with other processors, control of the input gain is greatly facilitated.
The Tone FX makes coloring of sound before dynamic processing possible. To do so, it groups together two types of processing functions:
- A 4-band parametric equalizer;
- An effect system making it possible to strengthen low frequencies and high frequencies.
The two functions offer results that are entirely different, which is why they are gathered on one single screen.
In Basic mode, use of the four parametric equalizers is simplified to the maximum. Only the gain for each correction is accessible. For FX Bass and FX Treble, dosage of the effect is also made accessible.
In Advanced mode, users have access to all equalizer parameters (gain, frequency and Q factor).
SOUND4 STREAM x4 has a true stereo enlarger, 100% mono-compatible. Its role is to sublimate the existing stereo image. It will thus never create stereo in mono sources.
The 3-Band Process
The 3-band Process is the heart of dynamic processing. The SOUND4 VOICE ULA algorithm guarantees the gain in each of the bands in order to complete sound stabilization. “Coloring” is controlled by the fidelity parameter. Thus, it is possible to have a purist and a colored sound texture.
The 3-band Process is achieved through the revolutionary algorithm S.I.S. (Sound Impact System), which makes it possible to maintain the authenticity of the original sound attacks.
The 3-band Process is extremely powerful and capable of absorbing very high variations of sound on its own, which is why it is not always necessary for the input AGC to operate.
The 4-Band Limiter
The main purpose of the 4-band Limiter is to prepare the work of the final limiter. It is also provided with a very powerful predictive algorithm, which has been simplified to the maximum, so that it is not encumbered with useless parameters.
The Brickwall Limiter
The Brickwall Limiter is an advanced algorithm which provides strong gain limitation, guaranteeing that there are no overs and no clipping.
