Audio directly input to output?

Is it possible in your JUCE app to configure that audio is sent directly from the input to the output ?

I’m developing an app (Win. iOS, macOS and Android) that is used when tuning guitars.

It would be nice if it was possible to pass the audio directly from the audio input to the audio output so the audio buffering deleay is avoided. It is quite disturbing with audio dalay when you play the electric guitar.

Why not just use a splitter and send separate signals to your device and to your amp or sound system? Your tuner app doesn’t need an output at all.
