Hi All,
I'm looking at AUGraph and thinking: hmm... I can construct many
independent number of AUGraphs and then string them together to form
one final mother-graph.
you can - there is a sub graph notion, however, when we looked at
AULab (which uses AUGraph) it turned out to really not provide any
additional value for us, so we just used the one graph and built up an
object around that that encapsulated all of the knowledge of the
topology of the underlying graph. To get some notion of how this is
assembled you can:
Use AULab to build a document,
Do a show on the document (there's a print command in the debug) menu
That shows you the graph, and then the collection of objects that we
created to abstract the various signal flows in an AULab session
I think it has some education value that is worth spending some time
with

But what I don't 'get' so far is how I connect AUGraphs together. I
had *assumed* that this was possible because of:
(a) the documentation says that we can do this (Audio Processing
Graph API - Core Audio Overview).
(b) the AUGraph API handles sub-graphs
Specifically; how do I connect an existing AUGraph that has a
generlc output into another graph? Assume that my input graph
consists of :
QT -> Pitch -> Generic
and that my output graph is:
Mixer -> HAL Output
how would I connect the generic output bus to one of the input
busses of the mixer?
Thanks
