     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.

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

     9 change output

    10 

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

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

    13 

    14 

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

    16 same through divergence.

    17 

    18 

    19 surprisingly, supporfEFX doesn't affect anything.

    20

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

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

    24 

    25 Setting audioNode paramaters changes the severity of the difference

    26 but not its onset.

    27

    29 Non-positional sound has no problems.

    30 

    31 

    32 Divergence gets worse the longer things run.

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

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

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

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

    39 aux cuts out at around 180 degrees.
