You've used size_t for num_channels elsewhere.

Not in this CL, at least as far as I'm aware.  I did a followon CL for channel
counts for you at https://codereview.webrtc.org/1238083005 , though it doesn't
convert these particular channel counts.

I'm definitely not going to add channel conversions to this CL.  I might try
adding it to that other CL, but remember that every time I touch anything I have
to touch the transitive closure, which is often hundreds of files.  It's just
infeasible to do too much at once -- this CL alone has taken some eight months
of my time.  I'm the only one doing this and I have to do it in pieces.

Understood, thanks.
