How to record audio for SIG21 course to use?

Describe the solution you'd like

1. We record everything from certain users' perspectives, e.g., record from the teacher's side and one of the students' side. Thus, OBS or similar software is enough for windows users. We need to figure out if Pico Neo has any video/audio support.
2. We record the audio via the program. So we can replay afterward for VR users to experience, in addition to only for video users to watch.
