What happens if noteOn or noteOff is called twice with different values after each other? 68783 1 olivier.thereaux 2012-06-07 08:17:22 +0000 [admin] Assigning items currently being worked on by editor. 68815 2 olivier.thereaux 2012-06-07 15:00:46 +0000 Change set from the editor: https://dvcs.w3.org/hg/audio/rev/5614c60b62e1 68816 3 olivier.thereaux 2012-06-07 15:01:21 +0000 More feedback from Philip in http://lists.w3.org/Archives/Public/public-audio/2012AprJun/0432.html « We'd prefer if the conditions were defined strictly in terms of playbackState. Suggested phrasing for noteOn: "If playbackState is not UNSCHEDULED_STATE, then the user agent must throw an InvalidStateError exception. Set playbackState to SCHEDULED_STATE." Suggested phrasing for noteOff: "If playbackState is UNSCHEDULED_STATE, then the user agent must throw an InvalidStateError exception." followed by the steps to schedule a playback stop. As you can tell, we don't think there's any point in disallowing multiple calls to noteOff. If we want to disallow it, a new playbackState will be needed. One can of course implement a hidden state, but it seems simpler and better to make readyState match reality. » 68868 4 philipj 2012-06-08 08:28:28 +0000 Actually, my suggestion is still not good enough. Quoting <http://wiki.whatwg.org/wiki/Howto_spec#Dealing_with_exceptions>: "It is important to state whether the algorithm should be terminate when the exception is thrown or not; in some cases, an algorithm will continue even after an exception is thrown (e.g. to do some cleanup)." In other words, "and terminate these steps" is missing. (That wiki page is a great read, we should take its advice on many issues.) 72703 5 olivier.thereaux 2012-08-24 15:03:55 +0000 Updating issue title to reflect (proposed) name changes from noteOn/noteOff to start/stop. 113866 6 olivier.thereaux 2014-10-28 17:13:45 +0000 Web Audio API issues have been migrated to Github.
