Slow down audio effect

I’m trying to duplicate the effect on the song “Hendrix” by “World Hip Hop Beats” (http://www.worldhiphopbeats.com) where the audio slows down. It sounds like a time shift of some kind. How can I do this with Audicity?

You could try the “Turntable Warping MS” plug-in http://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Turntable_Warping_MS
