Applications Built On Our Platform

Over 350 applications have been built using The Echo Nest's music data APIs and developer toolkits. Here are some of our favorites.

We unfortunately love to make things a bit complicated... In this case we took the opportunity to bridge one of the APIs (Echo Nest) up there in the abstract cloud, into a physical, mechanical structure, that rotates and creates permanent visualizations of the track data on various surfaces. An interesting blend of digital and analogue techniques! The details: Echo Nest Java API is used to analyze songs on a PC. The data is parsed and sent over WiFi to an Android 2.1 phone (Google Nexus One), The appropriate control signals are generated on the phone and sent over Bluetooth to a microcontroller. Microcontroller sends the appropriate control signals to a custom-built (see pics!) mechanically rotating arm, with a radially moving axis, so that we can cover a full circle with ink!
