DSEE HX
In addition to supplementing the high-
range sounds of music files, the sampling
frequency and bit rate are raised above
the original values to convert to a CD
(44.1kHz/16 bit) resolution or higher.
Suitable processes are carried out by
supplementing processes using AI (artificial
intelligence) technology to automatically
distinguish the type of song. In addition,
calculating signal processing in a 40 bit
floating-point and converting it to a 32 bit
fixed-point via the noise shaping process
allows for bit extensions and high-precision
frequency extensions, which far surpass the
normal 32bit precision.
The DSEE HX function works with the
following signals.

DSD Remastering
All PCM signals that are input are converted
to DSD signals of 11.2 MHz or 12.2 MHz. The
DSD remastering engine developed by Sony
converts the PCM signals to DSD signals
without losing the amount of information in
the original data.
