Steps to reproduce:

1. Go to this link: https://jsfiddle.net/umgmmqvp/2/
2. Open up console
3. Observer that the execution of the program abruptly stops at line 36 (`console.log(audioBuffer.getChannelData(1).length);`).


Actual results:

It seems to silently break the program and prevent further execution when I try to grab channel 1.


Expected results:

If there is no channel 1 available then I'd expect it to throw an error message.
Actual, use https://jsfiddle.net/umgmmqvp/3/ instead (slight fix to remove `.length` on line 36, because it is not relevant to this bug report). Sorry for the double post - I couldn't work out how to edit the original report.
