What is the range of the input sample data that the webaudio

/WebCore/Modules/webaudio/RealtimeAnalyser.cpp)?
Is it float values between -1 and 1, or is the data scaled
differently?
(I am trying to immitate the built-in logic of the AnalyzerNode, by
running a JavaScript side FFT on the time domain data that I am
getting in the "onaudioprocess" event of a ScriptProcessorNode. I am
using all the scaling/transformation logic from RealtimeAnalyser.cpp
but still my resuls are quite different from the built-in ones..)
I don't think you will get much help here. The mailing list webkit-help
is only to help with simple issues with the APIs. Question about the
implementation of WebKit are welcome on the list "webkit-dev".
Even on webkit-dev I am not sure you will get much help unless you have
a specific bug. That code has not really been touched in 2 years and the
original authors have not been active for at least a year.
One thing you could do to inspect RealtimeAnalyser in details is build a
debug build of WebKit, and run your code in your favorite debugger.
Good luck,
Benjamin
