I'm not familiar with boxer engines; I hear they can be quite noisy, but I'm not sure if this is normal. Here is a video I took of the noise. It is only audible during idle and seems to be coming from what I think is the crankshaft pulley.

Also, this can be unrelated, but there is a pulley that is shaking in the video. I marked it with a caption.

Anyone with boxer experience have any insight?

Update:
I took the car into the Toyota Dealer today (6/15), I asked for a mechanic to come and listen. About 7 people show up, about 3 or 4 of which are mechanics. Even the Foreman was there. One of them has a WRX so he was familiar with how noisy boxers can be. He was positive the cricket noise was coming from the Direct Injection system (primarily from the drivers side). He said the tension pulley was behaving normally; the shaking was normal.

Both he and the Foreman suggested I hold off on leaving it at the shop until they do some research with their corporate contact, primarily because they have no other FR-S or BRZ to compare it to. They said they would contact me next week.

Update 2:

The Foreman from the Toyota dealer just called me. He did some research and is 95% sure the noise we are hearing is the DI system, which switches modes depending on temperature and other factors.
