Landscape Photography: Isolating an audio problem

My website: https://www.andrewmartinphotography.org My Store page: https://www.andrewmartinphotography.o... Recently I have been experiencing a few issues with the audio on my vlogs and I have decided to try to isolate the problem so that I can find a resolution. I came up with a little experiment to help work it out and I have put that into practice in this vlog. I will be repeating the experiment next week in slightly different circumstances and the results of the two vlogs will determine how I respond. It may be a microphone problem or a connection with the GoPro, but it is a great opportunity to learn more about vlog production. In the meantime, if any of you have suggestions for resolving the issue please comment below. Cheers. Support me by buying me a coffee, or just a general donation, cheers.https://ko-fi.com/andrew_martin_photo....
