But is that really true ?
I mean - probably true for hardware issues (pen doesn't work or the audio recording malfunctions). But for more common occurrences of many people talking at once or someone mumbling - it is more likely that both will fail.
Yes, I was only talking about hardware redundancy. If I fail to capture the data I need to write complete and accurate minutes, that is my failure. And I need to be reliable, meaning my minutes need to be complete and accurate for every single meeting, consistently. So I need to make sure that I am able to capture all the data every single meeting. Having two recording devices gives me that hardware reliability since it protects me against a failure to capture the data I need.
If the failure is at the source, then having two devices won't help. So yes, if people mumble having two devices won't help with that. But I have other redundancies for those cases.
Also, the meetings are virtual on Microsoft Teams. So it is possible there could be a technical problem on the organizers end where the online meeting stops. I can't do anything about that. And there have been cases where the presenter had technical issues where they were not able to share their screen. I can't help that. Those types of failures would not be my responsibility.
For true redundancy you need a completely different mechanism (video with expert lip readers ?).
The two audio recordings is just the hardware redundancy. I have other redundancies to cover other possible failures like people mumbling. For example, I also take screenshots of all the slides presented on screen so that I have all the slides that were presented. Most of the time, I can get the information I need for the minutes from the presentation if the presenter mumbled or my audio was bad. The slides also contain the written motions that are submitted for votes. So I have the motions in writing to make sure that I am putting the motion in the minutes correctly. Many times, the presenter might refer to information that was also shared in a company memo. I can refer to that memo to find information I might have missed. This has been useful in cases where the presenter mumbled a name. I can look up the name in another source like a memo or email or website. I also get the reports that are presented during the meetings in advance by email. So I can refer to the reports for information I need.
Basically, in order to make sure I can reliably capture the data I need for accurate and complete minutes, I have many redundancies:
1) two audio recordings
2) screenshots of all the presentation slides.
3) transcript of the chat in Teams for any vote counts as well as any discussions or announcements that were posted.
4) reports from the presenters are submitted by email.
You might ask: why so much redundancy for just meeting minutes? Because it is the meeting of the Institute. The President of the university chairs the meeting. The dean and provost and VPs are present, as well as over 100 faculty. So yeah, it is pretty important that I don't fail.
With all those redundancies, I have never failed to submit correct and complete minutes.
