K2 is an information processing technology that enhances sound quality of digital sound sources, codeveloped in 1987 by JVC (currently JVCKENWOOD) and Victor Studio of Victor Music Industries (currently Victor Entertainment). 􀀀It features a number of proprietary technologies, including technology to analyze waveform data that tends to vary from moment to moment within the time domain. 􀀀Most notable is the fact that the technology was developed through rounds of testing and auditioning by Victor Studio engineers, who are experts in music and sound creation. Based on the vast amount of original master sound sources owned by Victor Studio, “K2 Technology” is a group of technologies that aim at faithful reproduction of the original source as far as possible by passing through the sound quality check carried out by the studio engineers who are thoroughly versed in audio and musical quality.
