Adobe has released the latest update of its audio program, Adobe Audition, formerly Cool Edit Pro 2.0 by Syntrillium Software. Including improved workflow and layout, Audition 1.5's new features range from VST plug-in support to pitch correction, to integrated CD burning and even a vocal extraction effect that works quite well.
I've been working with audio production as a hobby since 1997, and bought Cool Edit Pro in the summer of 1999. Although I have been eyeing Cakewalk's Sonar program lately, Adobe Audition remains an invaluable audio tool with one of the most intuitive, streamline graphic user interfaces on the planet. Check it out.
