Writing Web Audio API code that works in every browser - Developer guides
there's a section in the spec that lists the old names and their updated equivalences; be sure to check it out and change your code accordingly.
...for example, up until a couple of days ago pannernode did not support the default hrtf panning model yet, and attempting to use a pannernode with that configuration simply resulted in silence or a mono output coming out from that node, depending on the build you used.
... today the support is already present in nightly, but not quite yet in aurora.
... in the meantime, you can explicitly specify 'equalpower' instead: var panner = new audiocontext.pannernode(); panner.panningmodel = 'equalpower'; note that there's a list of projects built with the web audio api, specifying which ones use the standard audiocontext and which browsers do they work on.
