Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
I'm new to the Audiobus SDK and I'm having trouble getting my filter port working. I have input and output ports both working with the AudioUnit Wrapper. When when I connect a filter port to the same AudioUnit Wrapper, audio drops out entirely. I think the issue may lie inside of my filterPort's process block, because there is nothing in it.... I don't need to call ABFilterPortGetOutput right?
I provided a clientFormat, so shouldn't the filterPort just override what is coming in through the mic, for the input source audio, and take the audio that should go out to speakers, and send it down the line to the output App??? Does my filterPort process block need anything in it?
