           Summary: Spatialized panning renders incorrectly with
                    USE_CONCATENATED_IMPULSE_RESPONSES
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Audio

In a recent WebKit mac-port build or Safari 6 try:
http://chromium.googlecode.com/svn/trunk/samples/audio/simple.html

The spatialization is rendering incorrectly (compare to Chrome which doesn't use USE_CONCATENATED_IMPULSE_RESPONSES).
The Doppler demo also illustrates serious problems where up/down are scrambled:
http://chromium.googlecode.com/svn/trunk/samples/audio/doppler.html

This may also be an issue on the GTK port which builds with USE_CONCATENATED_IMPULSE_RESPONSES
