Abstract
Methods and systems provide a tool for assisting media players in rendering visualizations and synchronizing those visualizations with audio samples. In one embodiment, visualizations are synchronized with an audio stream using a technique that builds and maintains various data structures. Each data structure can maintain data that is associated with a particular pre-processed audio sample. The maintained data can include a timestamp that is associated with a time when the audio sample is to be rendered. The maintained data can also include various characteristic data that is associated with the audio stream. When a particular audio sample is being rendered, its timestamp is used to locate a data structure having characteristic data. The characteristic data is then used in a visualization rendering process to render a visualization.
