General Information
OVERVIEW
Much more than a simple Compressor
SOUND4 STREAM X 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).
SOUND4 STREAM X 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. SOUND4 STREAM X 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.
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 X is the
very first multi-channel AoIP processor dedicated to WebRadio bouquets. It has the capability of
simultaneously and independently processing a total of up to eight program streams on a single
PCI express card.
The SOUND4 STREAM X offers up to 8 inputs and 8 outputs through Audio Driver (WDM/
Direct Sound) and/or AES67/L. The streaming engine can provide 6 streams per channel
for an unparalleled total of up to 48 streams. Each stream is set on the latest codecs generation
(AAC, HE-AAC, HEAACv2 , as well as MP3 and more).
Advanced Coding Solution
In terms of encoding, the SOUND4 STREAM X offers a complete and innovative solution.
The SOUND4 STREAM X has a high quality encoding engine that suits every IP audio device
profile. Indeed, it is the first processor that includes adaptive sound optimizer for very low encoding
rates (16 kbps, 24 kbps, 32kbps).
Another clever bit of SOUND4 STREAM X 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 X adapts to most of the standards used for streaming delivery
systems - Wowza, Icecast 2, Shoutcast v1 & v2, etc as well as HLS.
