https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html#attributes-OscillatorNode defines the default 'type' as 'sine', but doesn't supply defaults for frequency or detune. However it is possible to create an Oscillator node and start it playing without explicitly setting values to these parameters.

I suggest the spec document the following defaults:

  'frequency': The default value is 440.
  'detune': The default value is 0.

These are unsurprising, and are what we're using in Firefox. Also sounds like what Chrome is using.

This is not controversial.

I pushed a spec change with what WebKit/Blink and Gecko do.
