> Possible. If only for audio playing purpose, you could try Video plugin and filechooser and in the video plugin .h264 url you input FileChooser.FileUrlAt(0) As source and then will play any sound source.
Yeahh.. That's smart. But is plugin Video works in NW.js? Because I heard it's not.
That i do not know, but you could try it out!
Edited: did a quick test and exported to winx64 seems the audio does not play on Nw.JS export packages with this aproach.
The 2nd solution is to use Tone.Js Api to play the audio since you are doing a C2 project. And use FileChooser same as above.
The only Downside to that is that Tone.js Plugin is in works for a while now probably 1 year or so, the last time i checked it it was lacking looping audio i think, which you might need.
If that is a no go, then what your left is modding the audio plugin or use Browser.ExecJs to create a custom audio media player that plays from the filechooser source url.
