Adaptive Noise Suppression adjusts the audio algorithm so you can cancel out the noise as it changes in the environment. Adaptive Speaker Equalization adjusts the 3 watt loud speaker settings based on volume selection so the sound is optimized for talker authenticity at lower volumes and speech intelligibility at higher volumes. Adaptive Gain Control adjusts microphone gain based on how loud you talk into the radio to ensure a consistent audio level on the receiving end. Adaptive Windporting engages a third microphone in order to cancel out wind noise.
