This scan found no usable audio input on this device. Webcams and virtual audio devices are left out, because RECAP needs a physical 3.5 mm microphone jack.
If you expected an input here: check that your operating system lets this browser use the microphone
— macOS System Settings › Privacy & Security › Microphone, or Windows Settings › Privacy & security › Microphone
— then scan again.
If there really is no input: a USB audio adapter with a stereo 3.5 mm microphone input adds one.
Don't use a studio audio interface that supplies 48 V phantom power — it can damage RECAP.
