I thought something like that was happening. But I'm curious: if a 2-channel
file is played over 4-channels it should go up an octave, should it not?
You'd
have half as much data for 4 channels as you'd have for 2 channels and so it
would seem like it's going faster? Or my reasoning is wrong somewhere (it
could
well be, I often get things like that mixed up)?

Hi Victor,
Would it be the case that Ardour etc are thinking
this is a mono
file? A stereo file played as mono could sound half-speed (maybe
somewhat distorted, depending on the differences betweeen the channels).
The problem seems to have been the data spread out over 4 channels instead
of 2, thus halving the output in terms of speed and consequently pitch.
Thanks.
Raymond
