How do I cache an Audio Stream from Media Player.

Hello there, I am trying to figure out how I can use the media player for a project I am currently working on for college.
I am successfully using a Stream Media Source in my Media Player, and I can hear the audio coming through my headphones when I play the Blueprint.
My problem is that I want to actually keep/save/store this audio stream in order to use it for a plugin I am trying to configure which usually runs on Mic Input, but can be used with a Byte Stream of an Audio File.

Basically, I want to keep the Streamed Media Source as an Audio File in my Blueprint for further use down the pipeline. Am I going a bit out of my depth? Or is this actually even possible? Please Help
