The name AUCH stands for AUdio CHecker. AUCH was developed to be a small, tool that simulates an elastic and reflective surface that vibrates with music. 

Vibrating elastic surfaces creates geometric patterns called 'Chladni Patterns'. If the surface is a non-uniform reflective surface is called a 'Makyoh'; Japanese for 'Magic Miror'. The application 'AUCH (AUdio-CHecker)' combines the two techniques to create a new way of looking at sound.
