Save audio input to be sent as a file on android.

Hello, I want to take the user’s microphone audio input and save it and then send it to a server via http request. I can capture the audio using the audiocapture module/nodes but the node saves the audio wav file to a path. how can i adjust this so the file is just saved within the game and then sent using an http request (as opposed to saving it on a user accessible file on teh android).
