QuoteTrackPerformer provides a stage for the visualisation of music. Rather than analysing the audio content of the music, though, TrackPerformer uses the notation -- the abstract representation of the music -- and allows one or more performers to "play" each instrument visually.There are a number of unique performers, as well as various pre- and post-filters that can be applied. TrackPerformer uses HTML5 Audio, and employs requestAnimationFrame (where available!) to keep things ticking along quickly and in time. Unfortunately, some of the filters require pixel-by-pixel manipulation of the canvas, and can be slow in some browsers and on older hardware. In testing, Firefox provides the best performance, followed by Chrome and Opera.
