Variable duty cycle square waves with the Web Audio API

> The given examples seem disconnected from the duty cycle radios on my browser. I mean changing them changes the sound, but it's as if the one I selected is not the one playing.

Confirmed. Author, please fix! For example, in the first set of radio buttons:

1. Leave it at the 50% default

2. Press play

3. Change it to the 12.5% option -- we continue to hear the same sound

4. Change it back to 50% -- finally we hear a different sound

This is broken. Another example:

1. Listen to 12.5% after having come directly from 25%

2. Listen to 12.5% after having come directly from 50%

The 12.5% should sound identical in either case, but it erroneously does not.

This is correct, the demo not properly handling the selection of a new duty cycle. I pushed up a correction just now. Thanks for laying out a detailed replication - made for an easy fix
