Sorry Marcus, I wasn't clear about that part.  The doppler effect uses the
.speedOfSound attribute in conjunction with the velocity vectors for both the
AudioPannerNode and the AudioListener.  These velocity vectors are in
meters/second and are independent of the units used for position and
orientation.  This is taken directly from the OpenAL specification.

Added more specific text for the setVelocity() methods and also added the
doppler shift algorithm which uses these values.
