This is a complicated WAD patch but the key thing is that the
frequency shifter is in the feedback path of the WAD (very slight
downshift). You'll hear it as the percussive sound which starts about
20 seconds in. Skip ahead to 4:30 to hear it most clearly.

P.S. the metallic sound does not use the WAD.
