Here's an odd problem I'm having; I am attempting to get the stereo difference of two audio inputs from JACK, (Each connected to the L or R channel)
[AUDIO IN "L"] - > Subtract |_
[AUDIO IN "R"] - > Subtract |
What I get however, is summed channels with some reverb. Same for adding the two inputs. As GNURadio does not allow JACK to have 2-channel input, this is the only way I can get Stereo audio into the graph.
