Dancer.js

Works exactly as the Winamp visualizer, allowing trippy animations inside web audio players.

All animations are in sync with the audio frequency.

A flash fallback is provided for older browsers.

What is new in this release:

• Use real-time audio waveform and frequency data and map it to any arbitrary visualization
• Use Dancer to get audio data from any preexisting audio source
• Leverage kick detection into your visualizations
• Simple API to time callbacks and events to any section of a song

What is new in version 0.3.2:

• Change build process to grunt.js.

What is new in version v0.3.0:

• Added ability to provide an audio element as a source -- can control audio via the element, or accessed through instance's audio property, or through Dancer's helper controls (play, pause)
• Pulled out loading from the constructor to the instance method load. Can use the above mentioned audio element, or a config object with path information.
• Changed instance method stop to pause, to be more in line with audio elements

What is new in version v0.2.1:

• Added getWaveform() method and a corresponding visualization for waveforms.

Requirements:

• JavaScript enabled on client side
