Fields
| Name | Value | Description |
|---|---|---|
| Unspecified | 0 | Don't do any directionality processing of the activated microphone(s).

| TowardsUser | 1 | Optimize capture for audio coming from the side of the device facing the user. In the typical case, a device with a single screen, screen-side camera/microphone and non-screen-side camera/microphone, this will be the screen side (as in a "selfie"). For a different device geometry, it is the side for which the expectation is to be facing the user.

| AwayFromUser | 2 | Optimize capture for audio coming from the side of the device pointing away from the user. In the typical case, a device with a single screen, screen-side camera/microphone and non-screen-side camera/microphone, this will be the non-screen side. For a different device geometry, it is the side for which the expectation is to be facing away from the user. This is the "taking a video of something else" case.

| External | 3 | Optimize capture for audio coming from an off-device microphone.

Remarks
Toward-user and away-from-user directions depend on the device's geometry rather than a fixed microphone index. External selects capture from an off-device microphone; unspecified requests no directionality processing.
