Capture input from two Microphones save to Wav about cscore HOT 5 CLOSED

Ok, you've got two major problems here:

The first is that you're setting FillWithZeros to true (in addition I would recommend to set DivideResult to false). This causes the mixer to serve infinite data. The result is endless loop in the DataAvailable handler. Set is to false. The second problem is that the SimpleMixer class does not perfectly fit for this scenario. The handler reads data until zero bytes got read. The mixer will remove the soundInSource from the source if its Read-Method returns zero. The result is, that the mixer will remove the soundInSource.

Apply the following modifications:
Set the FillWithZeros and the DivideResult to false.
Go to the SimpleMixer class and comment the following line:

Hi Florian,

Thank you for your help. I gave this a go and it does work but there is some noise being injected into the signal somewhere (possibly zeros from the buffer). I will investigate this further, and see if I can get to the bottom of it.

I'm also using the SimpleMixer class from the samples and I confirm that tick like sounds can be heard in the final audio (noise being injected as explained above). I applied the proposed modifications (Set the FillWithZeros and the DivideResult to false etc.)

Do you have any suggestions on how to correct this problem?

So you may try to set DivideResult back to true. As the name already indicates, it is just a "simple" mixer, demonstrating the basic principle. The clipping problem is not really solved. It is possible that a sample exceeds its valid range (-1 to 1). This can cause a "tick" noise. Settings DivideResult to true will prevent that case. But if you've got a weak signal, it will become even weaker.

Setting DivideResult to true solved the problem. Thanks.
