K-system, K-stereo and K-surround Bob Katz proposed the K-system to measure audio levels and standardize dynamic range in recorded audio. He has developed the proprietary systems K-stereo and K-surround. These processes are designed to "recover lost or amplify hidden ambience, space and imaging, and generate stereo from mono signals without adding artificial reverberation".
