KAR_DUET
Duet ON/OFF switch
Address: 0x8A
Type: R/W
Reset value: 0
Description:
The value in this register sets the duet function on or
off. When selected, the duet function is configured by
register KAR_DUETTHRESH.
KAR_DUETTHRESH
Duet threshold control
Address + 0x8B
Type: R/W
Reset delay: 0
Description:
When the Duet function is enabled by the
KAR_DUET register, this register specifies the ampli-
tude of the voice line below which the voice is can-
celled. If the amplitude of the voice line is below this
threshold, the recorded voice is played instead. The
value of DUETTHRESHOLD ranges from 0 to 255,
full scale signal.

KAR_VDELAY
Programmable delay/decay music effects
Address: 0x8D
Type: R/W
Reset value: 0x0
Description:
The value in this register specifies the delay used for
voice input effects. The delay can be set in the range
from 0 to 2048/Fs seconds (where Fs is the sampling
frequency in KHz).
‘desired time delay’ = ( 2048 / Fs) * ( Value / 256)
which gives:
KAR_VDELAY value = (Fs / 8) * ’desired time delay
For reverberation effects, this register gives the de-
cay factor,which can vary within the range 0 to 1.0.
