Use of sound card as a Digital Input port in a rather strange way...

Hey folks, got quite a unique one here...

I have managed to procure a device that receives IR signals and spits them out as Microphone level signals through a standard Jack socket as used on sound cards. What I'd like to do is to be able to use an old TV remote and this device to control my PC.

Using Adobe Audition I can see the waveform received is plenty strong enough and stands out very clearly from any noise aspect of the signal. In this software I can see that different buttons give different waveform shapes so on that basis one would think that you could look for "most similar" maybe?

If anyone knows of any software that might get me started I'd be very grateful. Anything that ties in with Autohotkey would be extra awesome :)

Thanks, BnC

can you please post photos of the waveform you receive? a better program to use instead of adobe audition for your application is a sound card based oscilloscope, i assume you don't have a real one that is.. an example of one is http://www.zeitnitz.de/Christian/scope_en
