I am using Juce Framework to develop my final degree project, which consist in coding a simple virtual audio mixer that manages 2 audio inputs and 1 stereo output. The mixer input channels process the audio signals coming from the computer mic/line input and from a multimedia player through a virtual audio cable.
Due to my rookie condition in setting audio devices and focusing my project mainly on real-time audio DSP processing, I chose the Juce Standalone Plugin template instead of the Audio Application template to code my project, but now, due to the input requirements I’m not sure if I did the right thing. In fact, the Audio/Midi Settings window only shows one stereo pair active input channels, and only lets me select one input device at a time.
What should I do to make the mixer process both input devices simultaneously?
