No. But there’s a way to keep the recording good enough to share without trimming.
Instead of having the Grain Recorder join the meeting as soon as you do, strategically wait until all participants have joined and the discussion is about to begin to allow the Grain Recorder to the meeting.
Similarly, when you sense the meeting’s important content has come to a close, simply “stop” the Grain Recording using Grain Desktop App.
This way, the water cooler banter of the first few minutes and the last few minutes won’t be recorded in Grain :)
