nit: Make these class members:

class AudioProcessing {
  static const int kNativeSampleRatesHz[];
  static const int kMaxNativeSampleRateHz;
};

in .cc
const int AudioProcessing::kNativeSampleRateHz[] = { ... }
const int AudioProcsesing::kMaxNativeSampleRateHz = ...;

I though about that, but there is no cc file. Is there another way around it?

[Andrew MacDonald, 2015/09/16 04:04:08]

You can use audio_processing_impl.cc.

Good point. Done.
