Commands
!<CR>
and
!AUDMODE-<CR>
are used to select
next and previous processing mode from the list of currently available
processing modes. Note: This is only true when Audio Modes are not
used (see below “
Audio Modes used
”).
Command
!AUDMODE(
X
)<CR>
is used to select a specific processing
mode, where
X
is a processing mode number as seen from Table 1 from
3.2.2. Please note that if a processing mode is being selected that is
currently not available, the command will simply be ignored and there
will be no feedback of this in the serial interface or anywhere else. For
that reason it is important to always offer the user processing modes that
are actually selectable. To achieve this, the controlling device should
always update the list of currently selectable modes using command
!AUDMODEL?<CR>
whenever signal type is changed
(
!AUDTYPE(XX,YYYY)<CR>
is received).
Command
!AUDMODE?<CR>
is used to find out which processing mode
is currently selected. The response for this command
!AUDMODE(
X
)<CR>
, where
X
is the processing mode as a decimal
number (see Table 1 in 3.2.2). This response is sent automatically
whenever processing mode changes if feedback level is 1 or higher.
The recommended way of implementing a processing mode selection in a
serial control device is:
1.
Use feedback level 1 or higher to get notifications of changed
signal type and changed processing mode
(
!AUDTYPE(XX,YYYY)<CR>
and
!AUDMODE(X)<CR>
). Use
these notifications to relay the information to the user.
2.
Whenever this notification about new signal type is received,
use command
!AUDMODEL?<CR>
to get the list of currently
selectable processing modes and only let user to select
processing modes from that list.
Audio Modes used
(“Use Audio Modes” in “Audio Mode Setup” is set to
“Yes”)
In this mode the user selects between special Audio Modes that are not
direct processing modes but a layer on top of that. By default these
Audio Modes are named “Movie”, “Music”, “Games”, “No Proc.”, “Custom
1”, “Custom 2”, “Custom 3” and “Custom 4” (as seen from Table 2 from
3.2.2). The idea is that the user selects a mode from this list depending
on what kind of content the user is listening. The processor then decides
which processing mode from the currently available processing modes is
the most suitable for the content. The installer can edit these Audio
