Good morning,
I've already made treatment to record audio with GetUserMedia. I used this example ( link ), it has the same js code.
The problem is that the framework I use requires a physical file (you can put more if you want) to send to the server. I have not found another way in GetUserMedia to do this because the audio is only in memory and it is not interesting to generate file in the browser.
I use the system on Android too.
Does anyone have any idea how to do this to send the audio to the server?
