 Okay so this is my experiment for how to record a phone call with a microphone and put both sources of audio into my GoPro Hero 5 Black and if it works for this then it would also work for a GoPro Hero 6 and a GoPro Hero 5 session. Here's the theory and we'll see if it works, I'll test it out with a phone call. For a pound I bought an audio splitter, then that splitter means that I can run one cable to the camera, hopefully there's a cable that comes with the splitter, that will go to the camera. Now the problem I had was that I wouldn't be able to listen to the call because it's being run into the camera, so the splitter means that I can plug in my earphones so I can listen in on the call. This is my GoPro Hero mic adapter, my lap of electronics, my crotch of audio, so then the other idea was to use this splitter, they're really easy to get on Amazon and eBay. So if I put this into the input, that jack is split into left and right, so I can put the phone in on the right hand side, so the phone audio will go to the right hand side into the GoPro Hero mic adapter and on the left hand side I'll actually put this microphone, which isn't plugged in at the moment, you're hearing me through the on-board camera on the GoPro, so I'll put this microphone, there you go, this is the Boyer BY-M1 and then make sure your Boyer BY-M1 is switched on and then all you need to do is plug the mic adapter into the camera. The fingers crossed you can now hear me through this microphone and I'll tap it. And then also hopefully, I've got the phone audio running in so I'll just put the earphone on and I'll make a call to my long suffering wife and I won't show you the number because she's a very busy woman. I know it's not working because I can hear the phone. Okay, so the problem I've got is my cheap splitter is a bit too cheap because it goes into the phone but not all the way to click and make a good connection. So I've got a barmy idea now, I'll use the splitter built into my Urban Ears headphones. So I've got my headphones on, so I'm going to plug in the Urban Ears to my phone and then they have a socket here you can use to daisy chain other headphones but if I run the cable that goes into the camera you should be able to hear what I'm hearing in the headphones. I'd rather not wear headphones in the videos but I guess it's the best I can do and also it's good because it means they'll be able to hear me through this microphone. You can hear me through this microphone which is going into the splitter. Take these earphones out they're not they're not needed and unfortunately my poundland splitter isn't needed so all I need to do now is to make another phone call to my long-suffering wife to see if this one works. Hi. Hi can you hear me? Very well, loud and clear. That's great and I can hear you in in both ears because I've got my big headphones on so the the test is to see if I can record a microphone and a phone call at the same time. It sounds like it works so at least you can hear me. Yeah really clearly. That's great. I was only calling to ask one thing can I use this on YouTube please? Yeah yeah. Great that's fantastic thank you. Okay. Bye. Bye. So it worked. I can't hear what you're hearing I need to listen back to this. I hope this has helped my god if you've got to this part of the video and it has helped why not give me a thumbs up or even subscribe I'm trying to get to a thousand subscribers at the moment that I'm on 211 it's never going to happen it's going to take years. If you need to subscribe you can give me now or help me closer to that dream. If you have any questions please leave a comment I'll try to answer them and if I can't then I'm sure someone else out there will be able to. Anyway I hope if you're searching for how to record a phone call and a microphone at the same time into GoPro Hero 5 Hero 6 or Hero 5 session this seems to be how you do it. I've now got to make some phone calls and put them on video. Thanks again for watching. Bye.
