Audio based autosplitter script written in Python 3.6. Basically it listens for the audio effect that plays when you complete a level (using a capture card), and simulates a keyboard press (numlock1) when it detects the sound.

NEW VERSION (2.0): Now an executable (.exe) that should not require any setup. Just unzip the .zip file and double click on GravityDuckAutoSplitter.exe

Note: I have not tested this on other setups than my own, so please let me know if it works for you :)

[For the tweakers/programmers: a lot of instructions and information is in the Python script itself, which I included as well.]
