C922 Pro Stream Webcam microphone . . .

Hello VUO Team,

I have a C922 Pro Stream Webcam. No problem receiving live video feed from it.

It is currently hung as an overhead stage camera, and I’d like to use the built-in microphone. The mic works in the Mac environment and shows itself as:

16/24/or 32KHz (selectable) 2ch 16-bit integer

Though the ‘Receive Live Audio’ Node lists the microphone as (Unknown Manufacturer: C922 Pro Stream Webcam), it seems unable to process the audio stream. Any work-arounds or suggestions?

Thank you in advance.

If memory serves me right, Vuo deals only with 48 kHz audio. If that is still the case, the 32 kHz limit of the C922 could explain the problem.

Maybe if the audio goes through a virtual audio interface like Blackhole or Loopback, the OS will be able to resample the audio stream to 48 kHz before sending it to Vuo.

Thank you @Kewl.

Just creating an aggregate device with the C922 mic and Blackhole worked perfectly.

Cheers,
William
