          Priority: P2
            Bug ID: 19704
          Assignee: crogers@google.com
           Summary: Acceptable range for value of AnalyserNode's fftSize
        QA Contact: public-audio@w3.org
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: olivier.thereaux@bbc.co.uk
          Hardware: PC
            Status: NEW
           Version: unspecified
         Component: Web Audio API
           Product: AudioWG

We discussed about FFT value back in May, and resolved that it was OK as a
power of 2, rather than being an arbitrary value:
http://lists.w3.org/Archives/Public/public-audio/2012JanMar/0506.html

We have however not addressed a related question about the value range for the
FFTSize. 

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. ]]
