Technical Overview
K2の技術概要
K2 is applied in a wide range of music production and music media manufacturing processes, and the two main technological features can be largely divided into the following.
1 高品位伝送技術
The name may make it look complicated, but it is just a technology for producing high-definition digital signal for digital data transmissions based on the K2 principle of "Closer to the Musical Truth." It is used to improve sound-quality changes and deteriorations caused by copying and in accordance with the type of digital equipment used, and it was designed to eradicate the various elements that cause changes in sound quality to preserve the digital data in its original state and to restore the digital data itself.

2 高音質化情報処理技術
The second feature is based on the other K2 principle of "restoring sound to its original state," .K2 is a technology that restores high-quality sound when digital data is processed. High-Fidelity Information Processing Technology is used when digital data has already been altered or deteriorated in order to be compressed or conform to formats or specifications that are restricted by the original format. It restores the damaged digital data to almost the same level as before being converted for compression and the original state.
In addition, High-Fidelity Information Processing Technology can pack into a CD the quality of up to 100 kHz frequency and 24-bit resolution. Instead of cutting them off, this technology modifies the signal to fit them into a CD, without reducing the overall volume of sound.
.Example: Music data up to a maximum of 196kHz/24-bits can be stored on a CD (44.1kHz/16-bits).
This uses unique technology to perform energy-equivalent conversion as music data in bands and specifications into which data that is usually reduced owing to the specifications being too large to be stored in that format. In addition, High-Fidelity Information Processing Technology performs sound waveform conversion processing which makes sound quality the optimal.This technology was conceived during the evolution of K2, and is generally used with the latest versions of netK2 and K2HD Mastering. デジタル化の基本原理から音質劣化について 基本原理から見たA/D変換時の歪の発生について K2技術の実施例
