VB.Net to test Camera, Mic and Speakers

~OSD~ 2,176

Hi,

On Windows 10, I need to test / verify if Camera, Sound and Mic are working properly or not. There are certain web sites that offer this type of services /tests.. but is f possible to perform these test with a .net form application?
I have not a clue, or starting point, so if it's out of the scope (advance level question), I will simply skip this.

Which type of tests ?
Sound/Micro status can be tested with Core Audio APIs (I had posted some samples)

If device is working / functional or not.
If you see your face in camera, camera is working fine.
if you can record your voice, your microphone is fine. Similarly, if you can hear your recorded voice, your speakers are also fine.

I can post a VB test sample adapted from MSDN (Capturing a Stream) which captures the sound /voice from the microphone to a WAV file,
but it is a bit complicated...

Then skip it. I will find some workaround (if possible).

I had already done the code a long time ago, the test looks like this :

Maybe some data could be added such a peak meter (like in this french site) or other things...)

Will go for 3rd party web sites that offer these type of tests instead as it will be complex to code .net for me to perform these tests.

Hi @~OSD~ ,
I'm afraid not.
Instead, you can use vb .net to open Camera,

Process.Start("microsoft.windows.camera:")

Record microphone input and play sound:

Using soundPlayer = New SoundPlayer("...wav") soundPlayer.Play() End Using

Hope it could be helpful.

Best Regards,

Yeah, the camera was straight forward, thanks.
However, seems like Sound Recording and Testing would be challenge.
