Science experiment - dual audio inputs

[Simcfc73]

Hi,

 

I have hit a bit of a wall and wondered if anyone else has doen this.

 

We have laptops in our science departmetn which have single audio input/output sockets. The science department have purchased little mikes to record soundwaves and the time it takes to travel between them.

 

They have a audio splitter and 2 leads coming out of them, they work fine on desktop machines but not on the laptops....they dont register as microphones on the laptops which I think is due to the single input. I did buy a couple of USB audio devices to test but they are just coming back as single channels.

 

Has anyone come across this before?

 

I did find a registry hack to force the socket to be whatever you decide but I would need to change it back after each lesson as they use them for headphone sockets too.

If the mics are mono (which they more than likely are!) could you MacGyver a cable together that takes one input to the left channel and one to the right channel with a common ground? Then you'd just need to use something like audacity to split the channels.
