I have begun to port PaiMorse to the Web. Taking a look on my options to manipulate audio in a Web app, I stumbled upon Audio API. It is not widely deployed yet, but it is very powerful and promising.

There are a number of powerful demos for Audio API, but not a simple tone-playing application or tutorial, so I decided to write a tutorial based on my first tests.
