Ideally the above enum would be named and these return and take the enum name, but I'm not sure that will compile given that the IDL uses unsigned short (try it). > WebCore/webaudio/AudioPannerNode.h:96 > + void setDistanceModel(unsigned model) { m_distanceEffect.setModel(static_cast<DistanceEffect::ModelType>(model), true); } It looks like DistanceEffect hasn't landed yet but at a minimum these should return and take unsigned short, if not DistanceEffect::ModelType (not sure whether that will compile while still having the IDL return unsigned short). > WebCore/webaudio/AudioPannerNode.h:139 > + Vector3 m_velocity; These should change to use FloatPoint3D, if not now then soon. > WebCore/webaudio/AudioPannerNode.idl:42 > + attribute long panningModel; Shouldn't this be "unsigned short" to match the types of the Panning Model values above?

Is it because the number of channels of the input to AudioPannerNode can't change at run time? Actually the number of channels *can* change, but the panning algorithms do not require any complex re-initialization to handle the different cases since they can simply call different code paths. >> WebCore/webaudio/AudioPannerNode.cpp:220 >> + if (elevation < -90.0) > > Presumably this should be "else if".

It's worth filing a low-priority follow-up bug against the code generators (I'm not sure which would be the best component; "WebCore JavaScript" is a guess) about that. 289303 8 69721 crogers 2010-10-04 16:51:37 -0700 Created attachment 69721 Patch 289304 9 69721 kbr 2010-10-04 16:52:47 -0700 Comment on attachment 69721 Patch Thanks for cleaning up that last nit.
