No, the file is split to two mono files and accordingly there's an 'L' 
or 'R' appended to the file name.

Well, indeed! The recording is 16-bit PCM while Ardour says it's working 
with 32-bit floating point. Telling Ardour to work with 16-bit integer 
reduces file size to half. Thank you for sorting that out for me.

I guess for my main use of Ardour to edit stuff for airing on radio, the 
extra hifi bits doesn't make much sense anyway.
