This is defined in wav_based_simulator and here. Can't we have it only once in
audio_processing_simulator?

[peah-webrtc, 2016/05/09 11:37:31]

I don't really follow this comment. As far as I can see, this enum is only
defined here, and it is only used within aec_dump_based_simlator.h. Could you
please clarify?

[aluebs-webrtc, 2016/05/09 16:27:32]

You are right. This is only defined here. My bad.
