Oh my... now wonder it is so confusing... "recordSampleSize" is NOT
the sample rate...

I don't know how rev would store an 11 bit wide word without waste.
Computers store info in their nice 8-wide world. It comes down to
parts and sanity. There are packing methods to do this - is that's
what's happening here?
Try a test. See if there is no difference in file size between
using 11 bit and 16 bit wide for RecordSampleSize
Confirmed, you are so right...
on recordSound
set the recordsamplesize to 11
set the recordrate to 5
set the recordformat to "wave"
record sound file gAudioTestPath
end recordSound
12 secs --> 184K
open in QT Pro, get movie props... it shows 16 bit, 8 khz
on recordSound
set the recordsamplesize to 16
set the recordrate to 8
set the recordformat to "wave"
record sound file gAudioTestPath
end recordSound
12 secs --> 184K
Same size, same quality...

- which is NOT the sample rate by the way - it is the width of the
word describing the voltage of the waveform at that slice of time)
-- the sample rate is actually set by the recordRate property
typical Rev misleading property and command names. At least
there's no DestroyRecording command.
If I used the sound features I would immediately bounce the params
from my own well-named commands and call them what I like. Also
define with standard rates in constants.
