Raised by James on 22nd March: http://lists.w3.org/Archives/Public/public-audio/2012JanMar/0460.html and documented in an action item: https://www.w3.org/2011/audio/track/actions/41 [[ For fftSize in RealtimeAnalyserNode in the spec, it only says the value must be power of 2. But in fact in the implementation, the value must be limited in the range of [128, 2048], and it will throw the exception if illegal value of fftSize is set. Which should be documented in the spec. ]] 85749 1 crogers 2013-04-08 21:52:07 +0000 Fixed: https://dvcs.w3.org/hg/audio/rev/7e5e69ce9ad8 86791 2 olivier.thereaux 2013-04-25 15:37:52 +0000 Changeset looks good.
