For MIDI applications, millisecond resolution is insufficient and can cause noticeable jitter. Using absolute wallclock time is also problematic, as it is subject to system clock skew. The MIDI timestamp should use High Resolution Time (DOMHighResTimeStamp), which solves these problems: http://dvcs.w3.org/hg/webperf/raw-file/tip/specs/HighResolutionTime/Overview.html 68819 1 olivier.thereaux 2012-06-07 15:06:57 +0000 Proposed changeset: https://dvcs.w3.org/hg/audio/rev/b78b7c5e906e 68820 2 olivier.thereaux 2012-06-07 15:08:00 +0000 Discussion thread since proposed changeset: http://lists.w3.org/Archives/Public/public-audio/2012AprJun/thread.html#msg497 76324 3 cwilso 2012-10-15 18:27:30 +0000 General acceptance of HRT. 77027 4 olivier.thereaux 2012-10-24 09:13:31 +0000 (In reply to comment #3) > General acceptance of HRT. From the e-mail thread (linked above) I see Philip expressed preference for seconds, but did not have a strong objection. Giving the group another occasion to object, but I think we have reasonable consensus around HRT at this time. 78348 5 olivier.thereaux 2012-11-15 09:58:54 +0000 (In reply to comment #4) > Giving the group another occasion to object, but I think we have reasonable > consensus around HRT at this time.
