this is where I got it....it is a plug-in called pacemaker
you can get it also from the link that trend gave and then push plug-ins at the menu on the top...then click on pacemaker to download...to pull it up on your winamp you push ctrl - K then you heighlight under plug-ins - DSP/effect and click start you will see a little window pop up where you can control tempo, pitch , and speed....any questions just ask :) -Robyn
