extra Anaylser node?
MaxiLib is creating an analyser node that seems unnecessary.
Mick says:
...in the earlier implementations of webAudio, there was a bug that meant if you attempted to start an audio analyser node later, it wouldn't attach properly, and so you needed to create it here, even if it wasn't being used.
I don't think we ever attach to this node? And I don't know if this bug is still an issue.
