ACTION-9: Side-by-side spec code examples

Provide side-by-side code-examples that demonstrate the simplest method of achieving the following task with the buffer & node based specs:
1) Getting audio from a source, silently.
2) Swapping the left and right channels of the audio.
3) Listening to the resulting swapped channels.

The code examples must include:
1) Audio Data API example
2) Node-Based Example (using JavaScript buffer processing)
3) Node-based example (without JS buffer processing)

Examples do not *have* to be working-examples, but should demonstrate the code that would be needed for the above tasks.

The purpose of this task is to highlight usability issues for developers. Comparing different methods of achieving the same goal with different APIs should give us some insight into how developers may feel when working with new code.
