High-Com II and III

Nakamichi, one of the more than 25 licensees of the High Com system, supported the development of a noise reduction system that could exceed the capabilities of the then-prevalent Dolby B-type system. However, it became apparent that a single-band compander without sliding-band technology, which was protected by Dolby patents, suffered too many audible artifacts. So, High Com was further developed into the two-band High Com II and three-band High Com III 2:1:2 systems by Werner Scholz and Ernst F. Schröder of Telefunken assisted by Harron K. Appleman of Nakamichi in 1978/1979. The two-band variant was eventually released exclusively as Nakamichi High-Com II Noise Reduction System later in 1979, increasing the amount of noise reduction on analogue recordings and transmissions by as much as 25 dB A-weighted.
