Processing mic input using node.js addon

[ItsMos]

Ive got the examples/addon.node working after building it, i could give it the jfk.wav file and get a result. But what i need is to get the audio from the mic directly (usually 1 - 2 second commands/words) instead of a file. I will be integrating this into my electron.js application.
How can i achieve this? although in the example it requires param fname_inp

What i did was save the mic recording into a file then process the file as a temporary work around.
