Projects / audio-checker


The aim of auch (audio-checker) is to visualize music. It takes audio from the microphone and uses it to simulate an elastic and vibrating surface (chladni-tranform) or the reflection of such a surface (makyoh-transform). Many more transforms can be activated by unlocking the interactive shell.

    Release Notes: This is a demo release. It shows Chladni patterns and/or Makyoh images of a vibrating, elastic, and reflective surface. Sound is captured by the microphone. The interactive console is disabled by default in the Windows build.

      Release Notes: The 'mirage toy' has two matched opposing parabolic mirrors to create an illusion: an object in the focus of one of the mirrors will be projected to the other focus, just like a hologram. This release simulates this device, but lets music reshape the mirrors, so the projected object looks like it is dancing. The idea was based on Leibnitz's Monads.

        Release Notes: Origami was used as an inspiration to create a moving 3D object that 'dances' to music.

          Release Notes: This version adds the visualization of the propagation of waves on a rope and "ether" (a different type of medium).

            Release Notes: This version adds surface waves to the tool. Both transformation and visualization of sound on different surfaces (such as rectangle, circle, hexagon, and triangle) are supported. The results are known as "Chlandi patterns". The transform supports both pre-recorded as live sound, so you can have an open microphone visualizing sounds. The documentation gives you a how-to, some examples, and a movie.
