SOUND4 IMPACT/FIRST/PULSE/Eco 2.x Unauthenticated Radio Stream Disclosure

Title: SOUND4 IMPACT/FIRST/PULSE/Eco <=2.x Unauthenticated Radio Stream Disclosure
Advisory ID: ZSL-2022-5734
Type: Local/Remote
Impact: Exposure of Sensitive Information
Risk: (3/5)
Release Date: 14.12.2022

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
