            Bug ID: 20681
           Summary: spatial coords should just be in metres
    Classification: Unclassified
           Product: AudioWG
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Web Audio API
          Assignee: crogers@google.com
          Reporter: giles@mozilla.com

Says,

"The units used in the coordinate system are not defined, and do not need to be
because the effects calculated with these coordinates are independent/invariant
of any particular units such as meters or feet."

This is true as far as the subsequent example goes, but is in conflict with the
doppler algorithm, which compares velocities against
AudioListener.speedOfSound, which is explicitly in metres per second.

I suggest the quoted sentence about unit independence just be removed, and that
the spacial fields be clarified to always use metres for length.
