The documentation for the Capturing Stereo Audio from Built-In Microphones sample app mentions:

"Starting in iOS 14 and iPadOS 14, you can now capture stereo audio using the built-in microphones on supported devices."

Question: Is there a specific list of devices that support stereo recording, or are all devices capable of running iOS 14 supported?

When I run the sample app on an iPhone X running the iOS 14 beta, the supportedPolarPatterns property for the built-in mic datasource does not include the .stereo option. Is that expected?

Thanks in advance for your help.

The correct approach here is just what you've done: query the supportedPolarPatterns property. As you've discovered, iPhone X is not supported.

Thanks for your reply!

Is there a complete list of supported devices?

My best guess is that this will match the list of devices whose technical specifications include the "Stereo recording" feature under the "Video recording" header, and this feature applies to more than just video recording. Is that assumption correct?

Currently, it’s supported for these devices:

iPhone XS
iPhone XS Max
iPhone XR
iPhone 11
iPhone 11 Pro
iPhone 11 Pro Max
iPhone SE (2020)
iPad Pro 11" and 12.9" (3rd generation)
iPad Pro 11" and 12.9"(4th generation)

To ensure future compatibility, though, you should always check the “supportedPolarPatterns” of the built-in mic’s data source to decide whether to enable your app’s stereo functionality.
