I need a program (for Windows) that continually 'listens' to a computers own audio ('what you hear' type, preferably).
Now, once it's 'heard' a set frequency it runs 'batch01.bat', at another set frequency it runs 'batch02.bat' etc.
The reason behind this is to play sounds on the PC that the computer will then react to.
Is this possible? I've been searching the web for a simple code/program but they all output to a graph or something.
My programming skills are limited to HTML and batch files, so please go easy on me :)
