A couple of suggestions for you.
Record it at normal speed then time stretch it to fit the length of time
you want it to play.
After the initial recording send the track through alsaplayer and adjust
the speed with the adjustable speed slider. Then record the new track in
ardour at 44100.
Mixing sample rates is probably gonna cause a big headache for your
session so make sure all the tracks you use have the same sample rate.
