Web Audio Offline Context and Analyser Node

Question

Is it possible to use the Analyser node in the offlineAudioContext to do frequency analysis?

I found out that ScriptProcessor

Answer 1

The analyser isn't really intended to be used in the offlineContext; in fact, it was originally named "RealtimeAnalyser". But even more importantly, right now you won't get consistent functionality from script processors in offline contexts, either.
