There could be something wrong with the way 'op' is used in
process_signal().

Suppose that run_eq() or run_eq_iir() is called with in_ptr == 0.
That means that the window is applied without any offset w.r.t.
the signal buffer. After the FFT, samples 0..127 in mid_buf have
their final value, accumulated over 16 windows, and are ready for
further processing. They are read via the index 'op' which
therefore should be equal to in_ptr, and not have the 'latency'
offset applied.
