Streaming Audio Visualizer for Holiday Chrome
This Chrome app builds up the holiday-chrome code base http://github.com/moorescloud/chrome-holiday, and implements a real-time basic visualization of the streaming Classical FM station.
THe visualization uses the Web Audio API to do a frequency-domain analysis of the incoming stream - which is a streaming Christmas music radio station in Germany. The visualization is also drawn to the display, so you it's possible to note the correspondence between the on-screen and Holiday based visualizations.
In essence, the Holiday is being used as the output of a spectrum analyzer.
This code can be adapted for your own sound visualization apps for Holiday by MooresCloud.
This use the super-fast UDP-based SecretAPI, which is documented at https://github.com/moorescloud/secretapi
