Max Recording Duration is defined as the length of an individual meeting.
For example, the Free tier has a limit of 1 hour. If a meeting goes over that time, then Read will leave the meeting and start building the meeting report for the data collected up until that point.
The paid plans offer an unlimited number of meetings per month. So you could have 50 meetings of an hour each and Read would measure all of those.
Read offers free or paid different plans. To see the full breakdown of pricing and which features are available with which plan, please see https://www.read.ai/plans-pricing.
For a quick overview of the main differences:
Each of the plans offer additional features and support on top of what the previous plan offers, and in this case, Max Recording Duration increases with each higher tier.
