           Summary: Throw exception in noteGrainOn if the grain duration
                    is longer than the buffer
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Audio
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: rtoy at chromium.org
                CC: crogers at google.com


In AudioBufferSourceNode.cpp, there is a FIXME comment about this.  While writing some layout tests, A typo caused my buffer duration to be very short and the grain duration to exceed the buffer duration.  Took a while to figure out why the grain was not being played.  An exception here would have been nice.

As currently implemented, if the grain duration exceeds the buffer duration, nothing is played.  Perhaps, whatever can be played from the buffer should be?
