Um, Beautiful.

Actually, 123.5usec is almost exactly twice of 1/16384Hz.
Because of the loop, we have 1/16384Hz delay. I wonder where we do have the delay.

In order to understand the behaviour of the system can I ask you to test the following things?

1) What are the delay without IOPs with f_sampl of 16k, 32k, 64k?

2) What are the delay with IOP with f_sampl of 32k, 64k?

Result:
TF agreed well with 2-time feCoeff4x and CDS time delay was -123.5 usec.
