Signal Processing
Methodology
A high-precision arithmetic algorithm that
was independently developed is used for
the input signal to generate an audio pulse
signal that drives the output stage.

Processing Block
8x Oversampling Digital
Filter
The oversampling digital filter processes
the PCM sound source up to 8 times*. The
process removes the excess noise and not
the audio, so the original audio remains
unaltered.
* Converted by 8x at 44.1/48 kHz, 4x at
88.2/96kHz, and 2x at 176.4/192 kHz
In music signals that have been digitalized
in a form called PCM signals, noise is
included for each fs, in addition to the
original audio. Although the noise must be
removed for accurate DA conversion, if you
use just the analog filter, it may damage
the original audio () (page 38) and
some noise may not be removed () (page
38). The 8x oversampling digital filter can
do batch conversions of music signals to
8fs (sampling frequency) / 32bit (bit rate),
without affecting the original audio, and
remove this noise via digital computations.
