audio-checker
The aim of auch (audio-checker) is to visualize harmonics in musical recordings. Many tools show the spectrum, but this tool focuses on one or two specific octaves, with an indication of the tonica, sub-dominant(IV), and dominant(V). This way, notes, chords, and harmonics in a musical piece become clearer. It also supports other types of transformation (like wavelets, surface waves, strings, resampling, etc). Another feature is that this tool can compare incoming and outgoing audio to test external filters.

Changes: 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.

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

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

Changes: 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.

Changes: The UNFOLD command simulates an expanding medium, ether, that propagates music from a sender to a receiver. This elastic medium is used to see if there is a fundamental invariable chord in a melody.
