The Adaptive Digital second-generation noise reduction (NR Gen 2) software is better at reducing background noise in speech signals under such circumstances where the background sound intensity levels are high. The algorithm can be customized to trade off between complexity, memory requirements, and required noise reduction. Higher MIPS is the trade off for the better performance over Adaptive Digital’s NR Gen 1 algorithm.
APPLICATIONS
Gen2 noise reduction is an excellent choice for applications with high background noise environments. Applications include traditional, mobile, and hands-free telephone systems, conferencing, speech recognition, and alarm systems.
