APPENDIX A: AUDIO SIGNAL FLOW
As noted earlier, all GALAXY processors offer the same processing for audio signals. However, the inputs and outputs are
different, so the signal flow is also slightly different. This appendix provides signal flow diagrams for all three processors and
a few more details about terminology.
COMMON TERMINOLOGY
For clarity, a few definitions are repeated in Table 1. The GALAXY processors can serve as both AVB Listeners (receive
networked audio data streams) and AVB Talkers (generate networked audio data streams).
Through the Ethernet ports, GALAXY processors can function as Listeners capable of accepting up to 8 Streams of
AAF/AVB audio input. Each stream can contain up to eight channels. An additional Stream serves a GALAXY processor
Clock Sink. Table 2 provides Stream to Channel translation.
The GALAXY processors can also function as Talkers through the Ethernet port. GALAXY processors are capable of
generating 6 output streams with varying output types further described in Table 3. An additional Stream serves as a
GALAXY processor Clock Source.
Table 1: Audio Input and Output Terminology
Name Description
Listener A device that is capable of receiving one or several streams
Sink A virtual input connector that is able to receive and unpack one stream.
Source A virtual output connector that is able to generate and transmit one stream.
Talker A device that is capable of transmitting one or several streams.
