Digital audio started with
Compact Disc and has since
given birth to such super
high-fidelity formats as DVD
Audio and SACD. There’s
another trend in digital audio:
compressed data formats.
Music distribution over the
Internet, silicon audio using
compact IC cards, and digital
broadcast by satellite -- all
these formats take advantage
of audio compression
technology. This means there
are two diverging trends in
digital audio -- higher fidelity
and higher compression.

JVC is not only a hardware maker but also a software producer as well, so there
has been a close collaboration between the hardware engineers and studio
engineers for all aspects of digital sound production. “K2 Processing Technology”
is one of the many improvements developed by this collaboration to achieve
higher sound quality. It was implemented as the “Extended K2 Processing,” a
critically acclaimed application to pure audio. The CC Converter is an adaptation
of this technology for compressed music. Therefore, it improves the sound quality
of both hi-fi sources such as CD and DVD (Linear Mode) and compressed music
formats including MP3 and WMA (Compression Mode), benefiting a wide range of
digital audio contents.
