I work at a non-profit that wants to do some two-person "Story Corps" type interviews, where two of our employees will take turns interviewing each other about their work. I expect about a dozen interviews, and then we likely won't use any equipment we buy ever again. Interviews will be in a small conference room. No soundproofing. The interviews will be shared online on social media. Our first approach was to just use the microphone built-in to someone's phone, but I think we can do a lot better without spending an unreasonable amount. What's the best way to upgrade this?
I've read some guides, including this one: https://www.thepodcasthost.com/equipment/recording-face-face-person-interviews-podcast/ and it seems like using two lavalier lapel mics is the way to go. Unlike the scenario in that guide though, the interviews will always be in one room, and we're not investing in a permanent setup. Would it be acceptable to record directly to the microphone input on a laptop or desktop, and if so, what do I use to connect two microphones? Or do I need to use a portable recorder, as recommended on that guide? Or is a USB audio interface to the laptop the way to go, with the same aforementioned dual lapel mics?
It's not likely we'll get a big budget for this. (I got some pushback for suggesting a $200 mic, but now I don't think a single mic will be the best choice anyway, compared to two lapel mics). At the same time, this will take a lot of staff's time to sit down and do the interview, so I want to get a good quality result.
