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

An alternative is to use the suspend and resume methods available for an OfflineAudioContext. After suspending, you can use your analyser node to get the desired time and/or frequency domain data. Since the context is stopped, this works just fine. If you're going to do this several times, you'll need to schedule a stop for the next time before resuming.

Unfortunately, AFAIK, only Chrome has implemented suspend for an OfflineAudioContext
