NOTE: All commands are terminated with an
ASCII carriage return character (hex code 0x0D),
represented by <CR> in the examples. All
responses are terminated with an ASCII carriage
return, line feed pair (hex codes 0x0D, 0x0A),
represented by <CRLF> in the examples. An
ellipsis (...) represents members of an array that
have been omitted from an example for the sake
of brevity.
inact (input activity)
This command is used to determine if an audio input
channel is active. An audio input channel is considered
active if it has less than 3 dB of attenuation assigned to
it by the automixing algorithm for some particular output
channel. Two forms exist for this command:
• Query for input channel activity on ANY output -
The input channel is specified by using the address
syntax. Addresses must be in the range 1 to 16.
The data type is integer, either “1” meaning that
the channel is active on at least one of the output
channels, or “0” meaning that it is not. If the channel
address is a wildcard, then the data type is an array
of integer of size 16.
Examples:
• Query for input channel activity on a SPECIFIC
output - An output channel/input channel pair
is specified by using the 2 dimensional address
syntax. Addresses for the first dimension (output
channel) must be in the range 1 to 24. Addresses
for the second dimension (input channel) must be in
the range 1 to 16. The data type is integer, either “1”
meaning that the channel is active on the specified
output channel, or “0” meaning that it is not. If the
input channel address is a wildcard, then the data
type is an array of integer of size 16. The output
channel address may not be a wildcard.
NOTE: This form was introduced with DM1624F
firmware version 1.2.0 and will will not work
correctly on earlier versions.
Examples:
Request
Response
Query
inact(15)?<CR>
OK 0<CRLF>
Query
inact(*)?<CR> OK
{0,1,0,...,0,0,0}
<CRLF>
incl (input clipping)
This command is used to determine if an audio input
channel is clipping, i.e., it is being overdriven by the
input signal to the point of saturating the analog to
digital converter. The input channel is specified by using
the address syntax. Addresses must be in the range
1 to 16. The data type is integer, either “1” or “0.” A “1”
means the channel is in clipping. A “0” means that it is
not in clipping. If the channel address is a wildcard, then
the data type is an array of integer of size 16.
Examples:
Request
Response
Query
incl(7)?<CR>
OK 1<CRLF>
Query
incl(*)?<CR> OK
{0,0,0,...,0,0,0}
<CRLF>
indel (input delay)
This command is used as a query to read the input
delay, or as an update to set the delay. The input chan-
nel is specified by using the address syntax. Addresses
must be in the range 1 to 16. The data type is integer,
in the range 0 to 2000, representing the time delay in
one half millisecond increments. If the channel address
is a wildcard, then the data type is an array of integer
of size 16. In this case the value
9999
may be used in
an update to indicate that a particular input delay is to
remain unchanged
by the command.
Examples:
Request
Response
Query
indel(1)?<CR>
OK 42<CRLF>
Query
indel(*)?<CR> OK
{0,40,0,...,0,0}
<CRLF>
Update
indel(15)+30<CR> OK<CRLF>
Update
indel(*)=
{12,0,...,8,9999}<CR> OK<CRLF>
ingn (input gain)
This command is used as a query to read the input
channel gain, or as an update to set the gain. The input
channel is specified by using the address syntax. Ad-
dresses must be in the range 1 to 16. The data type is
integer, in the range -10 to +60, representing the gain
in dB. If the channel address is a wildcard, then the
data type is an array of integer of size 16. In this case
the value
99
may be used in an update to indicate that
a particular input gain is to
remain unchanged
by the
command.
