     1 sqr-1khz, a mono 16 bit sound file, diverges at sample 9

     2 haydn, a stereo 16 bit,  does not diverge to 350 samples.

     3 pure, mono 16 bit, diverges at sample 9

     4 sqr-10Hz, a mono 16 bit, diverges at sample 10

     5 sqr-100Hz also diverges at 10.

     9 calling audioRenderer.updateSourceParams in main update loop doesn't

    10 change output

    11 

    12 audioRenderer.playSource vs source.play doesn't make a difference with

    13 pure (and probably doesn't make any difference)

    14 

    15 

    16 channel starts at -1, changes to 0 when playing starts, then stays the

    17 same through divergence.

    18 

    19 

    20 surprisingly, supporfEFX doesn't affect anything.

    21 

    22 

    23 When things are off, they only appear to be off by one byte.  main

    24 will be at x and aux will be at x+1 or x-1.

    25 

    26 Setting audioNode paramaters changes the severity of the difference

    27 but not its onset.

    30 Non-positional sound has no problems.

    31 

    32 

    33 Divergence gets worse the longer things run.

    37 As the sound source moves about the listener in a circle, the sound

    38 should be at a constant volume, since the distance between the source

    39 and listener is constant. Instead, the sound varies depending on where

    40 the thing is in the circle.  Main cuts out at around 90degrees, while

    41 aux cuts out at around 180 degrees.
