Puede procesar ocho canales en una única tarjeta PCI Express simultánea e independientemente. Tiene ocho entradas y salidas. La Sound4 x8 es compatible con redes Windows, Livewire y (muy pronto) Ravenna. Con respecto al procesamiento, la Sound4 x8 tiene una cadena de procesamiento real: AGC + FX tono (ecualización paramétrica de cuatro bandas/ecualización de dos bandas) + FX estéreo + compresor de tres bandas + limitador de cuatro bandas + limitador tipo muro (brickwall).
En cuanto a la codificación, codifica cada salida a un máximo de cinco flujos. Cada uno puede corregirse de manera independiente (procesamiento adaptativo) para compensar las diferencias en sonido ocasionadas por la codificación. Una emisora puede personalizar flujos según la audiencia destino: audio de baja velocidad de bitios para dispositivos móviles, una velocidad de bitios más alta para escuchar por Internet. La tarjeta maneja MP3, AAC, HE-AAC, HE-AAC v2.
Con respecto a los metadatos, Sound4 x8 admitirá diferentes normas y el puente de datos XML permitirá una integración total con suites de automatización de la emisora. La tarjeta es compatible con servidores de medios populares como Shoutcast, Icecast, Wowza, Flash, Darwin y Helix. También es compatible con numerosos sistemas de automatización conocidos de ENCO, BSI, BE, Nétia, RCS, y Winmedia, entre otros.

Wide Band AGC...
In Sound4 x8, the first processing function is the “Wide Band AGC”: it is an automatic gain control operating in broad band. Its main purpose is to “level out” gaps of levels applied at the level of the processor.
The algorithm specially developed for this AGC is of the predictive type. It allows very high sound variations without any sort of pumping. Compared with other processors, the facility of control of the input gain is incomparable.
The Tone FX...
The “Tone FX” makes coloring of sound possible before dynamic processing. To do so, it groups together two types of processing functions:
A 4-band parametric equalizer;
An effect system making 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 “Easy” 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 “Full” mode, you have access to all the parametric equalizer parameters (gain, frequency and Q factor).
The Stereo FX...
Sound4 x8 has a true stereo enlarger, 100% mono compatible. Its role is to sublimate the existing stereo image. It will thus never create stereo on mono sources.
The "3-Band Process"...
The “3-band Process” is the heart of the dynamic processing of SOUND4 x8. A single 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 colored sound texture.
The “3-band Process” is provided with the revolutionary algorithm S.I.S (Sound Impact System), which makes possible to maintain the authenticity of the original sound attacks.
The “3-band Process” is extremely powerful, which is why it is not always necessary to make the input AGC operate, being capable alone to absorb very high variations of sound.
The "4-Band Limiter"...
The first 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 in order not to be encumbered with useless parameters.
The Brick Wall Limiter...
The Brick Wall Limiter is an advanced algorithms which provides a strong and rock solid gain limitation.
