           Summary: WaveShaperNode not functioning properly
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Major
          Priority: P2
         Component: Web Audio
        AssignedTo: webkit-unassigned at lists.webkit.org

WaveShaperNode has setCurve functionality to set the user defined curve.
But as per W3C the curve should get arrange between values -1 to 1, with 0 being as centre.

Here below is the example:
                var value = new Float32Array(3);
                value[0] = 0.1;
                value[1] = 0.23;
                value[2] = -1;
                value[3] = 0;
Use setCurve to set this curve to node. Then after processing WaveShaper node; expected output is
                value[0] = -1;
                value[1] = 0;
                value[2] = 0.1;
                value[3] = 0.23;

The following more on this, WaveShaperNode.h has process method which should eventually call WaveShaperProcessor::process() to perform the expected functionality. But the WaveShaperProcessor::process() function is not getting called.
