</h1>
<p>This page tests the <code>createOffer()</code> method. It creates a peer connection, then prints out the SDP
generated by <code>createOffer()</code>, with the number of desired audio <code>MediaStreamTrack</code>s and the
checked constraints. Currently, only audio tracks can be added, as there is no programmatic way to generate
video tracks. (Web Audio is used to generate the audio tracks.)</p>
