VIAS was originally a software to measure and evaluate the acoustical properties of bowed instruments. In its new extended form, it is a tool for measurement and analysis of any musical instrument, hence its name: Versatile Instrument Analysis System.

What can VIAS be used for?
for admittance measurements and evaluation of bowed and string instruments such as violins, cellos, harps, guitars, pianos, and percussion instruments, with help of the impulse hammer or shaker method
for extended and more accurate impedance measurement and analysis, including audio tests of the measured instrument based on the measured or calculated impedance curve
