8. Audio IO
8.2.3
Subscribing to Streams
Audio from streams on the network can be connected to POWER CORE either statically (by assigning a source
from a RAVENNA streaming input) or dynamically (by configuring RAVENNA Pool Sources).
In both cases, you will need to define the streaming inputs as follows:
1.
Open the "Audio Input" branch of the 'Tree Definition', and select one of the RAVENNA In tabs.
Note that the number of channels available is dependent on the POWER CORE license. At maximum capacity,
up to 256 channels of audio can be received via 128 streams.
Note that streams are received on either or both
network topology.
2.
All inputs which are named can be used by other elements within the configuration; for example, as the
audio input to a source. The other parameters configure the input's audio options and stream setup.
The first few fields: Name, Type, Dig Offset Gain, Matrix enable and Transparent are handled in an identical
manner to other audio inputs. See
The RAVENNA parameters: Stream Size, UDP Port No, etc. define the stream setup.
The important fields are:
·
Name - a name must be entered in order to use the input.
·
Type - defines the format of the input: mono, stereo, etc. This should match the Stream Size.
·
Matrix enable - by turning ON the Matrix Enable option, the input can be controlled by a matrix.
·
Stream Size - defines the number of audio channels used from the stream. This should match the
audio input format (Type) to maintain conformity. However, this is not a requirement. If the stream size
does not match the type, then the audio inputs will still be assigned when a stream is subscribed to,
with consecutive channels being allocated on a one-to-one basis.
·
UDP Port No. - reserved for Unicast operation.
·
Default Stream (optional) - defines the name of the stream you wish subscribe to. It can be used to
permanently link the receiver to a stream. You can enter a stream name of up to 28 characters. The
console will then search the network using mDNS or SAP announcement protocols. If a matching
stream name is found, the receiver will automatically subscribe to it. If a Default Stream name is not
entered, then an automatic subscription will not occur. In this instance, a stream subscription can be
established by selecting a
·
Matrix No. - when the system is used in conjunction with an external routing controller, such as Matrix
Server, this number corresponds to the entry in the Matrix Server configuration.
3.
Repeat these steps to configure the inputs for each RAVENNA stream.
