Osmosis is an interative spectrogram visualization tool for you to tinker with electronic music and see how your tinkering is reflected on the 3D spectrogram.
The spectrogram displays audio frequencies from 20Hz to around 12000Hz (bottom to top), and uses height (3D depth) to illustrate the amplitude of the audio signal.
The "GENERATE" tab gives you the options to choose from different audio sources and elements. Oscilattor could be used as an audio source, or different parts of music.
The "FILTERING" tab gives you a couple of audio signal filters like High-pass or Low-pass filter to process audio, and you can see such changes reflected in the spectrogram visualization.
Mouse-left to rotate spectrogram, mouse-right to move spectrogram. Mouse-wheel to zoom in and out.
