Q: I've imported an audio clip into audacity and want to play about with the speed but when i click on effects menu its all hidden (coloured grey) is there something else ive got to to

A: Have you selected the clip? Press Ctrl+A to select all or "paint" with the mouse the portion of the clip you want to change. You can also make selection from Edit/Select -menu. After selection you can apply effects from the Effects-menu.
