Hi,  
I am trying to do a music visualization (oscilloscope like) in p5js.  
The audio signal comes from [vmix](https://www.vmix.com/help25/index.htm?ExternalOutput1.html) program using NDI protocol.  
I need to input this audio signal into p5js sketch in order to draw the visualitzation.

Could P5js capture NDI audio input? Or is there any trick via browser or… to do that?

Thanks in advance!!

Are you using the NDI Virtual Input? You can use that to get the NDI audio as just another input that you could tell your browser is a mic input.
