While music streaming services are gaining ground, vinyl records are regaining popularity these days and a return to analog sound is underway.

One reason for this is that the sound of records is said to have warmth and emotional appeal. Analog sound sources such as vinyl records contain frequencies in the high bandwidth of 22kHz and above, which are not contained in CDs or compressed digital sound, and are inaudible to humans.

Recently, one theory suggests that these higher frequency bands have a soothing effect on the human mind, and those sounds may work to make the sounds we actually hear more pleasant. The appeal of sounds unique to analog, which are said to retain far richer expressive power than digital, is now being reevaluated.

K2 technology recovers music information above 22kHz (high-frequency bandwidth) that is missing in Bluetooth transmission and reproduces high quality sound that is extremely faithful to the original sound.

K2 technology was developed based on the "Closer to the musical truth" philosophy, which emphasizes the creator's thoughts and feelings that went into the original sound source. By approaching the quality of the original sound, K2 technology enables the expression of even the most minute nuances, such as a performer's breath, the atmosphere of the place, and the sense of presence.

K2 technology performs upscaling processing and high-frequency bandwidth extension using K2 parameters. These K2 parameters were carefully selected from among approximately 4 trillion combinations of original master sound sources accumulated at the professional Victor studio, and contribute to the perfection of original sound restoration.

Even if other companies were able to create a similar program, they would not be able to duplicate the parameter settings selected from the quadrillion possible combinations. This substantial know-how encompasses K2 technology and our unique advanced sound quality technology.

Restores the high-frequency harmonics that have been cut from compressed audio, using a proprietary algorithm and parameters derived from a quadrillion possible combinations. This reproduces sound approaching the quality of the original master.

Especially with music such as classical and jazz, the music is reproduced with a realistic feel including the sound of breathing and the rubbing of strings. The presence of the performer can be felt with a sense of being there.
