Hi to you all,
Im pretty new in this forun and also on node red.
Has part of my final high school project i need to record audio (via user mic) from the dashboard and play it through the raspberry pi speakers.
- I have searched the web alots of times but i didnt found the answer.
- I dont use the Microphone UI node becouse its doesnt integrated with my other Dashboard Nodes. (When i put this node in the editor, i cannot see any other UI nodes in the dashboard.
- This is flow i am trying to use
(A dashboard tempmete to implement browser recording to the sox play node):
