Position in the Product Line

The SOUND4 IMPACT has no competition among the FM/HD processing PCIe-card-based tools not only in the SOUND4 product range, but also on the market all over the world.

An innovative solution based on the latest technological developments, the SOUND4 IMPACT is a multi-functional product of advanced capabilities. Besides being a cutting-edge FM processing tool, it also provides a number of options whose price would constitute a 30-50% price increase if offered by a separate product, such as Basic and Full RDS, WebRadio Streaming, SOUND4 IP Connect (IP codec), local audio backup. The SOUND4 IMPACT effectively combines performance with cost-effectiveness to make it the smartest choice on the market.

The SOUND4 IMPACT is also the first product in the range having unique features that significantly improve FM reception in degraded environments. When developing the product, all of the users who participated in the tests in critical environments found a significant improvement in terms of reception, which guarantees a larger audience in places where frequencies are disturbed.

 

A Unique Processing Chain

The SOUND4 IMPACT incorporates a unique processing chain with an innovative approach which is even described as revolutionary by its first users.

A common problem users report is related to loudness variation between old and new titles. In some cases, the auditor may even decide to switch the radio station during sequences of old and recent titles. This is a concern for many program managers because a changing sound leads to loss of identity, and the auditor does not recognize their radio.

With SOUND4 IMPACT, all these inconveniences are a thing of the past. The 2-band AGC is based on the signal strength and no longer on the electrical average values. It automatically detects differences in loudness to smooth out variations in sound perception. Its structure ensures perfect stability and enhanced vocals combined with a good bass presence.

Another problem frequently observed in FM comes from variations in reception levels when the moving receiver switches from stereo to mono and vice versa. These changes affect the tone (loss of treble) but also the overall level of sound perception, so the sound "goes up and down" in addition to a “changing sound”.

The SOUND4 IMPACT introduces an innovative process - mono and stereo parts of the signal are processed separately to obtain perfect homogeneity in terms of both sound and level. Therefore, in moving reception, when the FM receiver switches from stereo to mono and back to stereo, the sound variations and changes in level are reduced by over 90%. In the SOUND4 IMPACT processing chain, the stereo expander can then be used substantially without any limitations.

But there is even more to the SOUND4 IMPACT, which sets it apart from any other product available on the market -a 3-band limitation section after the 6-band processing of dynamics. There is an easy answer as to why only 3 bands are used. This is due to the fact that the outputs of the limiter are added and they then feed the final limiter. The sum of the signals on three bands induces less variation in levels than in the case of 6 bands. The final limiter job is then more stable and therefore less subject to distortion when the processor is used for an important parameter such as loudness.

Moreover, when it comes to loudness, the IMPACT is at the same level as the best, most popular and well-established products on the market. The structure of the final limiter consists of 3 limiters - one for basses, one for FM and one for the MPX. This is guaranteed to meet the expectations of the most demanding programs managers.

 

Optional IP Audio Codec Solution

The SOUND4 IMPACT has an empowered IP audio transport built-in option which allows for audio signals to be carried into IP from the studios to multiple transmitters. This option is called SOUND4 IP Connect, and can transmit a signal to up to 32 destinations.

It is possible to re-broadcast a link to other locations without decoding and re-encoding. Security is at the heart of SOUND4 IP Connect, which offers backup links with automatic switching, a multi-gateway to use several modes of transport on the same card, alarm management with SNMP and an Alarm Stacker.

 

Basic or Full RDS Encoder

The SOUND4 IMPACT includes a basic or a full RDS encoder option, the latter being UECP-compatible.

 

Six Streaming Encoders

The SOUND4 IMPACT can perform Internet radio broadcasting for all types of media. It has six fully configurable encoders supporting MP3, AAC andHE-AAC v1 and v2. This option is compatible with the most popular servers (Icecast, Shoutcast, Flash, Wowza).

Better yet, this option has the Adaptive Process for very low bitrates (i.e. HE-ACC 24kbps). In this case, a compensation algorithm corrects the codec in real time in order to make sure that quality loss is minimal.

 

Integrated Audio Backup Solution

Much more than a mere processor, the SOUND4 IMPACT has Audio Backup functionalities. Due to the capacity of its hard disk to store audio files, it is the first processor that guarantees continuity of the on-air program, solving the problem of radio silence.

 

Link & Share

Like all PCIe card products, the SOUND4 IMPACT is compatible with Link & Share. This is a Telnet-like protocol that makes integration easier. All parameters are externally accessible and it is even possible to create scripts that will be sent by the broadcast automaton to change a PS, an input in mix mode, an IP route or an audio Preset. The SOUND4 IMPACT offers a large number of possibilities for the top performance that customers need.

Input State

The SOUND4 IMPACT has four inputs - Digital, Analog, IP (Livewire or SOUND4 IP Connect) and PCI.

On the software interface, the input currently in use is indicated by a triangle on the left side of its name.

 

2-Band AGC

With the SOUND4 IMPACT, the first processing function is the 2-Band AGC - automatic gain control whose main purpose is to stabilize the loudness level applied to the input of the processor and prevent noticeable level differences between recent and old titles.

 

Tone FX

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).

 

Stereo FX

SOUND4 IMPACT 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.

In addition to embellishing the stereo image, it also has a 3-band stereo image limiter acting on the control of the energy transmitted by the stereo sub-porter at 38 kHz. This unique functionality limits issues currently caused by the traditional enlargement processes. The stability of reception in areas disturbed by multiple routes is thus greatly optimized.

 

The 6-Band Process

The 6-band Process is the heart of dynamic processing. With SOUND4 IMPACT, 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 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 Limiter

The main purpose of the 3-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 4-Band Parametric EQ

The parametric 4-band equalizer is by far the most impressive feature of the SOUND4 IMPACT. It is not there to "build a sound"; it allows some last little touchup if necessary before the final limiting section.

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).

 

The Final Limiter

The Final Limiter comprises two sections - one for FM applications and one for HD applications.

The FM Section consists of a Bass Clipper, guaranteeing powerful bass without distortion, an FM limiter and an MPX limiter.

The HD Section is specifically designed for high quality digital applications (HD/DAB/DRM). This is a look-ahead type of limiter and in this mode the outputs are not limited to 15 kHz.

 

Assignment of Outlets

The outlets of SOUND4 IMPACT are fully assignable. For example, the analog outlet may replicate the signal which is applied to the analog input, the digital outlet delivers an HD signal, the TX1 outlet delivers the MPX signal and the TX2 outlet drives the 19-kHz pilot signal.
