I would like to send a boolean value from a sound processing application to a running Urho3D application on the raspberry pi4, under Raspbian; and be able to send an integer from the Urho application to the sound processing application. All this should be in realtime.
The sound processing is being done externally to Urho but it consists of an FFT IRR filter and some more processing to extract a frequency/note from an audio snippet. And also sending a frequency/note out onto a sound card.
Does anyone has any idea how this can be done, on the Urho side?
