Alsaplayer sounds crap in varispeed. I'd use Ardour for slowing things 
down as it uses libsamplerate for that purpose. In the Mixer strip, 
just above the pre-fader plugins, it says "1" which is for playback 
speed of that track. [Shift-] Click that to change it. You can then 
export to wav or whatever.

Yes. But I take it from other messages in this thread that you have 
trouble running jack with higher rates. No clue what's in the way.
