retrofit - Sending raw audio data file from Android app to Node.js server

Question

I am new to android and node.js;

My task is as follows:

I have a raw audio file on my android device. The goal is to build an android app to send the file to my Node.js server, where I can then convert the data into playable audio.

Currently, using retrofit, I am able to succesfully send data of type T from the android device to my server. On the server side, I am able to convert a raw audio file (assuming that I already have it on the desktop) to WAV format and play it in the browser.

How do I extract the raw audio file on the android device and send it to the Node server?

Thanks!
