A system for providing an acoustic image that visually represents sound includes a light source, a liquid membrane, a sound source and a display device. Light from the light source is directed at one face of the liquid membrane as the sound source generates sound waves that are directed to the liquid membrane. The liquid membrane vibrates at resonant frequencies, changing the surface area of the liquid membrane. Light is reflected off of the liquid membrane as interference color, and captured as an image which provides a high fidelity translation of the audio signals that varies in pattern and color based on the audio signal.
