Sound possibilities that make a difference
Sound librairies
At SOUND4, we believe a flagship product should offer multiple processing structures, providing an "à la carte" approach. This delivers diverse sound possibilities, transforming our product into a Swiss Army knife for any audio requirement. SOUND4 IMPACT FM .CL is the only processor in the world offering this unique flexibility!
Voice Smoother
It's well-known that voices can sometimes be compressed or over-clipped after passing through the final on-air processor. IMPACT FM .CL is equipped with multi-stage voice smoothing technology that optimizes vocal clarity, even when the processor is pushed to its limits.
Fidelity Control
Fidelity control is a sophisticated feature that allows for a spectrum of audio experiences, ranging from faithful reproduction of the original source to deeply coloured and richly textured sound. This versatile tool enables users to fine-tune their sound signature, adapting it to various needs while maintaining high audio quality.
Reducing streaming artifacts
SOUND4's advanced algorithms intelligently process high-frequency content, significantly reducing digital artifacts commonly associated with compressed audio streams. This results in a cleaner, more transparent sound, particularly beneficial for digital broadcasting and online streaming platforms where maintaining audio quality across varying bitrates is crucial.
Adjust band positions by fine-tuning their crossover points
IMPACT FM .CL features multiple band processing structures with adjustable crossover points. This key point empowers users to craft their own distinctive sound signature. In GUI, a beautiful logarithmic graph displays band distribution and provides access to crossover points.
Wide or 2-band AGC
The AGC (Automatic Gain Control) stage in a broadcast processor is crucial for correcting input level differences. In IMPACT FM .CL, we offer two processing structures: a wideband structure for natural sound control, and a two-band structure for more in-depth spectrum control.
6-band De-Clipper
Unique to the flagship IMPACT FM .CL, the de-clipper stage fulfills two crucial functions. First, it mitigates distortion from over-mastered input sources. Second, it enhances density and/or dynamics, serving as a powerful tool to boost the sound's punch and depth.
6-Band Process
At the heart of sound sculpting, the 6-band process is essentially a mega AGC equipped with a unique algorithm, making it one of the pillars of SOUND4 IMPACT FM .CL processing structure.
6-Band Limiter
Preparing the final limitation, controlling peaks and increasing loudness and density, the 6-band Limiter is a unique design that never smashes the sound or loses attacks. The HQ Sound processing engine is again a crucial part of this stage.
Final limiter
The final limiter in SOUND4 IMPACT FM .CL offers a range of unique features, whether you're aiming for a powerful sound that cuts through the radio dial or a subtle, refined audio experience. Its advanced capabilities make it highly adaptable to diverse audio needs and broadcasting scenarios. This versatility allows the limiter to excel in both bold, attention-grabbing applications and more nuanced, sophisticated sound processing.
R128
SOUND4 IMPACT FM .CL is meticulously designed to adhere to industry-standard loudness regulations while maintaining precise control over true peak levels. This advanced audio processing solution empowers users with the flexibility to adjust the loudness threshold according to their specific requirements, all while preserving the integrity and clarity of the original sound.
Listen IMPACT.CL Processing Engine...
This player allows you to listen to some audio examples processed by IMPACT FM .CL. You can hear the difference between "Unprocess" and "Processed" files. This gives you just an idea as it's impossible to demonstrate all the capabilities of IMPACT FM .CL with just a few examples!
That's why we recommend trying it yourself with our 30-day demo license, which lets you process your own favorite sources through the amazing IMPACT FM .CL.
No one else offers such an HTML-based graphical interface!
At SOUND4, we pay great attention to the user interface experience. Ergonomics is our aim, but we also provide functions that make users confident in their use of the product. You'll never feel lost, and our undo/redo function offers a solution to go back and forth if you're not satisfied with your changes.

Advanced Final Limiters - Bass + FM + MPX
This final limiting stage incorporates our latest technological advances to significantly reduce distortion. A dedicated low-frequency limiter feeds into the final limiter, which delivers a powerful, competitive, and exceptionally clean signal, even at very high MPX power levels. An MPX limiter then controls the remaining peaks. The exclusive Embedded Pilot feature increases the final signal level by nearly 1 dB. The final limiter also includes MPX power regulation, ensuring strict compliance with the ITU-R BS.412 standard
