I want to record ambiences for 5.1/7.1 SUrround!
Unless you're getting a 2nd order or above mic, I
will recommend that you don't get an ambisonics mic. Instead, record in a regular shape (square or hexagonal for 51/71 respectively). This will give you better separation for surround, and will sound noticeably better on speakers. Using Ambisonics itself necessitates a bit of speaker bleed, which is only remidied by going to 2o or above. This sheet documents all ambisonics mics which are available for purchase, I can find, for completeness.
The main point of using ambisonics these days IMO is to (cheaply) capture in 3D. For 3D surround, Pro Tools 12.82 supports 9.1 (712) for atmos. You can then buy a 9.1 decoder for 3D surround ambiences. You can also record directly with mono mics in 3D surround (again, regular shapes preferred).
There's nothing special about ambisonics mics, they're just mics arranged in a regular shape for coicident capture, chosen & calibrated, then combined & dealt with holistically.
