Can a web browser use multiple audio sources concurrently?

Question

I have a computer with multiple audio out ports on the sound card. Can I use the web audio api or something to play different audio source to different output ports?

For example, in a browser, load 3 tracks and send each track to a different audio output port on the sound card.

Answer 1

Hmm. The channel splitter seems to have more fine grained control of audio channel. I'm not sure if that is what I would need though. One multi channel audio source to multiple monos?
