| Parameter | Description |
|---|---|
| deviceName | The name of the device. |
| minFreq | Returns the minimum sampling frequency of the device. |
| maxFreq | Returns the maximum sampling frequency of the device. |
Get the frequency capabilities of a device.
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 minFreq and maxFreq parameters return 0, 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 16000 or 0 even when recording at other sample rates works. Use the returned values as a hint rather than a strict constraint on these platforms.
