Comment:
 If multiple audio tracks are enabled simultaneously, they are mixed.

It would be great if it is possible to use the WebAudioApi for mixing 
multiple audio tracks .

Usecases: 
- Preview LoRes-Video-Proxy files from professinal Cameras with multible
Inputs. And Level them in a small Mixer.
- HTML5 Video&Audio Sequencer Applications.
- Contol Atmo Volume seperately.

Interesting idea, how would that work?
Comment 2 Chris Wilson 2014-08-06 17:09:38 UTC
It seems like the only thing necessary to enable this is to change the MediaElementSource definition in Web Audio to create one output per track on the media element node, rather than a single output.

Comment 4 Ian 'Hixie' Hickson 2014-09-11 23:13:56 UTC
Chris, does Web Audio have a Bugzilla component I can pass this over to? It sounds like something that should be handled on the Web Audio side rather than in HTML.
Comment 5 Chris Wilson 2014-09-12 00:19:46 UTC
we ditched our bugzilla in favor of gh issues - https://github.com/WebAudio/web-audio-api/issues.
Comment 6 Ian 'Hixie' Hickson 2014-09-12 16:24:41 UTC
Chris, ah, ok. Do you have an issue tracking this in particular? I couldn't find one in the list.
Comment 7 Chris Wilson 2014-09-12 16:55:20 UTC
We do now.  :) https://github.com/WebAudio/web-audio-api/issues/352

(Sorry, was on mobile before.)

Cool thanks. Marking this WONTFIX for HTML.
