My thinking here was that there's a couple of nodes in the spec that are
perhaps hard to specify mathematically (the compressor node, for
example) and that even if we could, my preference leans towards
attempting to specify the intended effect while leaving implementations
to compete in terms of performance or sound quality. Is that even a
desirable goal?

In the case of the HRTF setting for the Panner node my preference would
be:

- allow developers to load their own HRTF into the Node[1]
- word the spec such that an implementation MAY provide a default HRTF
  set, and if they do,
- it SHOULD be derived from the IRCAM set that Webkit have used up to
  this point.

Thoughts?

Cheers,

Chris



[1] we've spoken about this before and I know it's probably a bit tricky
    to implement and specify. We (the BBC) could help with the
    specification, at least.
