The spec doesn't seem to have this kind of check, but since we have it elsewhere and I don't know the background, not going to complain.

From the spec [0]:

> "Attempts to create new Nodes on the AudioContext will throw InvalidStateError"

Documentation updates should now be complete. In addition to listing ConstantSourceNode on Firefox 52 for developers, I also mention the addition of AudioScheduledSourceNode (its parent interface) and the fact that other interfaces were updated to also be based on AudioScheduledSourceNode. See below for a list of the main pages which were updated; there were other pages changed in small ways as a side effect but were not tracked.

Pages added:

https://developer.mozilla.org/en-US/docs/Web/API/AudioScheduledSourceNode
https://developer.mozilla.org/en-US/docs/Web/API/AudioScheduledSourceNode/onended

https://developer.mozilla.org/en-US/docs/Web/API/ConstantSourceNode/ConstantSourceNode
https://developer.mozilla.org/en-US/docs/Web/API/ConstantSourceNode/offset

https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API/Controlling_multiple_parameters_with_ConstantSourceNode

Pages updated:

https://developer.mozilla.org/en-US/docs/Web/API/ConstantSourceNode
https://developer.mozilla.org/en-US/docs/Web/API/ConstantSourceNode/offset (now redirects to AudioScheduledSourceNode/offset)
https://developer.mozilla.org/en-US/docs/Web/API/ConstantSourceNode/start (now redirects to AudioScheduledSourceNode/start)
https://developer.mozilla.org/en-US/docs/Web/API/ConstantSourceNode/stop (now redirects to AudioScheduledSourceNode/stop)

Some of the updates above also include changes to deal with the change of base class for several node types to be AudioScheduledSourceNode. In addition, these pages were similarly revised:

https://developer.mozilla.org/en-US/docs/Web/API/OscillatorNode

These pages were updated because I saw they needed help while working on the above changes:

https://developer.mozilla.org/en-US/docs/Web/API/OscillatorNode/OscillatorNode
https://developer.mozilla.org/en-US/docs/Web/API/OscillatorNode/type
https://developer.mozilla.org/en-US/docs/Web/API/OscillatorNode/setPeriodicWave
https://developer.mozilla.org/en-US/docs/Web/API/PeriodicWave
https://developer.mozilla.org/en-US/docs/Web/API/AudioContext/createPeriodicWave
https://developer.mozilla.org/en-US/docs/Web/API/PeriodicWave/PeriodicWave

This page was added to help explain and understand some points:

https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API/Simple_synth

Example snippets and explanations added (or determined to be unneeded on the following pages):

https://developer.mozilla.org/en-US/docs/Web/API/ConstantSourceNode
https://developer.mozilla.org/en-US/docs/Web/API/ConstantSourceNode/ConstantSourceNode
https://developer.mozilla.org/en-US/docs/Web/API/ConstantSourceNode/offset

On top of all that, I updated a couple of MDN’s database macros to ensure that their information on this API is up to date.
