This is a simple android app that bridges audio from your microphone input to your speaker output.
It's intented for use with other system audio routing apps like sndcpy. One method of usage is:
Microphone -> InstaPlayback -> sndcpy -> [Network] -> [Receiving Device]-> Remote Speaker
This basically allows your android device to be used as a remote microphone over a network.
To run it, clone and open the repo in Android Studio. There are no dependencies so the build should be straightforward.
