I have recorded meetings in the past and although, as is obvious, it can be a life-saver to capture 100% of what is said in the meeting, it is time consuming because in order to document, you will have to listen to the entire meeting again, at least once, if not take even more time.
Here are a few comments to consider:
What is the purpose of the notes and who is the audience? I have recorded meetings, taken the time to document every important point, distribute the meeting notes and found the level of detail to be overwhelming and too much for my audience to gain any advantage.
You may need to only capture enough information for executive leaders to refer to in the subsequent meeting(s).
In cases where the meetings are say, higher level project meetings, it may be necessary to just document action items, decisions, as well as issues and risks which should have actionable information (who, when, what, etc.).
In periodic project meetings, often the basis of the agile scrum practice is useful, which is:
1. what did you do in the prior period
2. What are you going to do in the upcoming period
3. What obstacles are you facing
Note: there is also a parking lot concept for any item not related to the above three items.
In my experience, the critical items are action items and decisions. These are those things that need to be tracked, reviewed and revisited by project management staff.
You may want to give that a try, in conjunction with your recordings to see how that works out. In such a case, you will have the recording as a backup.
I hope this helps and good luck!
