Can I capture audio from Dashboard 2? I can see that a node was created for dashboard 1 (node-red-node-ui-microphone), and for DB2, I found @5minds/node-red-dashboard-2-processcube-audio-capture which seems to work (generates the UI), but does absolutely nothing when I click on Start.
If you follow the link from the node's page on the flows site to its github repository you will see that does not exist, which suggests that the node is abandoned. I think you will have to find an alternative route. I don't know the solution myself.
[Edit] Copilot does suggest a solution using the browser MediaRecorder API in a ui-template node, but I can't vouch for whether it works.
