+    Constructor(AudioContext context, optional AnalyserOptions options),

The spec says BaseAudioContext instead of AudioContext, but it's sort of
nonsensical to use Analyser on the OAC. Still, we should think about this.

I think you're looking at the old version of this file. I updated them all to
say BaseAudioContext.

But with suspend/resume, AnalyserNodes work just fine on offline contexts.
