What sample rate is Ketai audio input?

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 and here

You can go a bit further by exploring the definition of Android AudioRecord’s constructor if needed.
