So being able to diagnose stuff is really important. And so we were in a venue or they were in a venue. We started off from the start the sound was not great, but it was fine. I could hear it okay, and I recorded it. My first point was to ask the venue to just get a recording on a mobile phone. Just set an audio app, record the audio, put it in a nice out of the way place near the speaker. We'll see what we get. So that was kind of my backup. The first 15 minutes were actually okay, they were YouTube bubble. The second 15 minutes started to degrade. Now I don't know why this is an even now because I wasn't on site and we've moved on in terms of diagnosing what that particular issue was no idea. I suspect there was a microphone open somewhere or a speaker that was closer to the microphone. And just over time the feedback just built up enough so that it started to echo into the speaker. That's what it sounded like. One of the solutions could possibly have been to have plugged in a pair of headphones so that that signal got taken away from from the space but I wasn't there. The way it was set up would have meant walking in front of the speaker so all that stuff wasn't possible. So the second 15 minutes. Not great on the edge of being acceptable for YouTube without any processing but the final 30 minutes oh my god. It was it was it was echo delay. Almost there was it was almost you could hear it twice. So it must have been coming from somewhere. Maybe it couldn't have been it might sometimes you got Oh has someone in the audience got them their mic on for the zoom. But it was in webinars so there was no mics to be open. The mics that were open. Were in the room were off. So it wasn't that possibly the sound coming out of their speakers. And their laptop might have been affecting it but they would have heard that and they tried to turn it off. Anyway. It got so bad that I had to God mic to the digital audience. We had 120 130 people on the live stream to say, terribly sorry. As you can hear we are having an audio issue. It isn't something we're going to be able to fix. I was quite honest at that point to say this is as good as it gets. I didn't say that but that's basically what I was saying. We're going to take the recording that we have taken from the audience in the venue because we kind of suspected this might happen. And we will put the slides and we'll go out. The other thing on top of this is that because of where the projector was, and the camera had been situated, it washed out the slides so we couldn't actually see the slides. And because I wasn't operating the slides, I didn't have a copy and the Zoom being remote access it's not something that I would have in that situation. But great behind the scenes backwards and forwards. I was sent the app. I was sent the slide deck, which was in PowerPoint, but I'm on a Mac and as soon as I opened it, it's formatting just went all over the place. So I had to save it out as a PDF and open it in the PDF reader and just share that and just scroll past then discovered that the slides I had been given was a lot bigger deck than the slide deck that the speaker was using. So the slides are mine were not what was on the screen. And I couldn't always see what was on the screen in the venue. So when I I was having to open up the thumbnails down the side I mean this is diagnosing output in real time. I was opening up the thumbnails at the side of the PDF which the audience would have been able to see but I had to make that decision and see if I could match up what was how far we gone. Pick that slide. Take someone else off and go back to that so they can see the slide. And in the chat after I'd made the announcement. Indeed people did. Hopefully saw the funny side of it. A lot of people stuck around. I mean, it's it stayed at over 100 for the entire session. The q&a was just a nightmare. I mean, you couldn't really hear anything. I mean, they did take questions from the zoom. But it really it wasn't audible by this point. So at the end, people even were there right at the end. I mean fantastic. But being able to diagnose something that's happening in real time isn't really feasible.
