Computer Graphics
The cathode ray tube made possible the oscilloscope, an early electronic device that can produce images that are easily associated with sounds from microphones. The modern Laser lighting display displays wave patterns produced by similar circuitry. The imagery used to represent audio in digital audio workstations is largely based on familiar oscilloscope patterns.
The Animusic company (originally called 'Visual Music') has repeatedly demonstrated the use of computers to convert music — principally pop-rock based and composed as MIDI events — to animations. Graphic artist-designed virtual instruments which either play themselves or are played by virtual objects are all, along with the sounds, controlled by MIDI instructions.
In the image-to-sound sphere, MetaSynth includes a feature which converts images to sounds. The tool uses drawn or imported bitmap images, which can be manipulated with graphic tools, to generate new sounds or process existing audio. A reverse function allows the creation of images from sounds.
Some media player software generates animated imagery or music visualization based on a piece of recorded music:
- autom@ted_VisualMusiC_ 4.0 planned and realized by Sergio Maltagliati. This program can be configured to create random multiple visual-music variations, starting from a simple sonorous/visual cell. It generates a new and original audio-visual composition each time play is clicked.
