Note about the digital filter during PCM playback
FIR-type digital filters
This type of filter has an established reputation for sound quality
and features tonal quality with both dense, rich sound reverbera-
tions and crisp sound transients.
Short Delay-type digital filters
This type of filter has no pre-echo in the impulse response and
features natural sound attack and reverberation for a tonal qual-
ity that is close to the original.
DSD digital filter
This sets the type of digital filter used when converting DSD signals
from digital to analog.
