No :-) Sure, two channels is still the most common delivery format

(eg. as individual regions in a multi-channel editor session), and for
delivery, the six-channel "5.1" format is becoming pretty common.
So in the audio world, by convention we talk about bit depth per
channel, not total. If the graphics people used our conventions,
they'd talk about a "16-bit, 3 channel" image, rather than saying "48
bit" and leaving the number of channels implicit. (Which is
weird. What about when you switch color spaces, eg. from RGB to CMYK?
Is it still 16 bits per channel? Do you call the CMYK file a "64-bit"
file or what?)
Conversely, if the audio world were to adopt the conventions of the
graphics world, we'd talk about CDs as "32-bit" audio. But we don't :)

Yes, but this 48bit representation of color is
just 16bit x3 colors
[channels]. In other words the 48bit representation is 3 unrelated
16bit [channel] representations concatenated, one each for the 3 primary
colors/CCD sensors. The equivilent for audio would be just 16bit as
there is only one channel.
Hmmm, wouldn't there actually be TWO channels for audio - stereo?
