The J and L keys can be used to shuttle (scan) through the timeline at various speeds. By default, Premiere Pro adjusts the pitch of any audio that is present. If you prefer the more traditional result, where pitch rises or falls with a corresponding increase or decrease in playback speed, there is a setting that can be changed. Inside the Audio section of the Preferences menu, turn off the option “Maintain pitch while shuttling”.
