Passing null or an empty string for the device name will select the default device. You can use the _devices property to get a list of all available microphones.

When both and parameters return , the device supports any frequency.

Note: On Android and iOS, the returned values might not reflect the device's actual capabilities. The minimum and maximum frequencies are often reported as or even when recording at other sample rates works. Use the returned values as a hint rather than a strict constraint on these platforms.
