How to play two audio streams simultaneously? mp4 format

Nvidia's Geforce Experience has the option to save two audio tracks: one for game and incoming sound, and another for your microphone. This is great because then in video production I can use a noise filter and adjust the mix of my microphone separately than the rest of the audio. But when I just want to watch the recently captured videos, I can only select between the two tracks with right-mouse > "Audio" > "audio streams", which shows two aac recordings. How do I play them together? I can do it in WMP but only with complicated command extensions.
