DSP SETTINGS > DELAY
The
Delay
section allows the user to apply a delay to the signal, visualise it in different units and
determine the total delay. This screen has the following three sections:
-
User added delay
: This is the delay defined or added by the user depending on the specific needs
of his application.
-
Preset delay
: Depending on the preset enabled or selected, the system may include an additional
delay. This delay is added by the current preset and for some factory presets, it can be also edited.
-
Total DSP delay
: Total sum of "
User
", "
Preset
" and internal DSP latency. It is not an editable
parameter and is only shown for information and reference.
The "
User
" and "
Preset
" delays can be defined in three different units, corresponding to the editable
parameters in the first two delay sections:
-
Samples
: for 48 kHz sampling rate.
-
Time
: Delay in milliseconds (ms), referred to the 48 kHz sampling rate.
-
Distance
: Delay in meters (m), referred to
c
= 343 m/s.
When changing a parameter in any section, all the other parameters are updated with the corresponding
value in their units.
