PreVox™ AGC is a proprietary automatic gain control module designed for digital voice communication systems. It provides a wide gain range (up to 42 dB) without introducing distortions to the input speech signal. Optimized as a pre-processor for parametric vocoders, it works especially well in conjunction with PreVox™ Neural/Signal noise suppressors, ensuring superior speech quality for modern communication systems.
