I have always concidered melodyne to have some quite magical technology. They are one of the only software music companies that has products that are truly revolutionary. Gizmodo refers to their latest application as 'photoshop for music'. However I would consider applications like Adobe Audition and ProTools to be more analogous to photoshop. Melodyne is a level deeper then this. They have tools that allow you to decompose and reconstruct music signals in ways that are simply never seen before. Melodyne is showing a holy grail of music software technology here. It increases the usability and flexibility of music components by an order of magnitude. DNA would be like photoshop if photoshop could take an image, decompose it into actual 3d objects, edit them, and then recompose the image. here, link.
