Since the timestamps are not propagated, it does not appear possible to add effects to a particular point in the media resource timeline. For example, audio descriptions (voice synthesis of extra text cues for the visually impaired) requires ducking the main audio and mixing in additional audio at a specific time. 113893 1 olivier.thereaux 2014-10-28 17:14:09 +0000 Web Audio API issues have been migrated to Github.
