the PCM samples are supposed to be -1.0 to +1.0 from core audio
devices. they shouldn't be -3.98 to +3.98.

Hello,
I am working on a quick project that monitors the samples during a
soft play through. I'm looking at and basing a some of my code of off
the AudioThru example. It looks like the value range for the incoming
samples is -4 to 4 (actually something like -3.98 to 3.98). I'm not
sure what i was expecting the range to be, but this is not it. Is this
range standard? Standard for Linear PCM? Or might other devices use a
different range? It seems like the sort of thing that you would query
the device for (like you would look for the format of the stream,
sample rate, etc.). Is that right? I can't seem to find a property to
be looking for. Thanks, Justin
