I am using ketai audio input on android apps created with processing, but I cannot find its mic sample rate and ketai’s reference is not described.  
Do you know the mic sample rate or how to find?  
Thank you.

I check Ketai’s source code [here](https://github.com/ketai/ketai/blob/master/src/ketai/sensors/KetaiAudioInput.java#L19) and [here](https://github.com/ketai/ketai/blob/master/src/ketai/sensors/KetaiAudioInput.java#L39)

You can go a bit further by exploring the definition of Android [AudioRecord](https://developer.android.com/reference/android/media/AudioRecord.html#AudioRecord(int,%2520int,%2520int,%2520int,%2520int))’s constructor if needed.
