• Fast scroll using a small preview of all the signal like sublimetext
• Implement magnetism :

  • to simplify editing annotations that are single-sample wide
• Keyboard shortcuts for fast annotation

Run the application

There are two usable files that you can simply open with your browser (after cloning/downloading this whole folder):

• example.html: as its name exaplains it, it's an example. The data displayed by example.html is loaded from test_data.json.
• app.html: this is the final app that is currently under active development, you can try the implemented features, the format of the json file must be like this:

{"values": [0.45,0.88, 0.98, 1.35...]}

Development

This application is developped as a library file : annotator.js that might be used anywhere else, example.html and app.html are example usages of this library.

It only depends on the excellent Concrete.js library : http://www.concretejs.com/
