Visualization techniques range from simple ones (e.g., a simulation of an oscilloscope display) to elaborate ones, which often include a number of composited effects.
[3][4] Subsequently, PC computer music visualization became widespread in the mid to late 1990s as applications such as Winamp (1997), Audion (1999), and SoundJam (2000).
In particular, MilkDrop (2001) and its predecessor "geiss-plugin" (1998) by Ryan Geiss, G-Force by Andy O'Meara, and AVS (2000) by Nullsoft became popular music visualizations.
AVS is part of Winamp and has been recently open-sourced,[5] and G-Force was licensed for use in iTunes[6] and Windows Media Center[citation needed] and is presently the flagship product for Andy O'Meara's software startup company, SoundSpectrum.
Richard Burn, a PhD candidate at Birmingham City University, as of 2015, is researching a device that displays detailed visual feedback from electronic instruments.
[8] Researchers from the National University of Singapore have also created a device that seeks to enhance musical experiences for deaf people.
They have developed an interactive light studio in the American Sign Language and English Lower School in New York City.
