Noisebud has updated the multiband image editor Skyline to v1.5.
Except for bug fixes and some GUI changes the new main feature is the 'Spread' control. 'Spread' will either make your side/difference channel more lush and airy or stereoize the mono content in your mix to add that depth and 3D feel that's so sought after and that at almost no effort. Skyline will also keep your track 100% mono-compatible, it is created with ease of use in mind.
There are two options, one free and one priced at $19. The free version has no limitations and is identical to the $19 version but has a recurrent nag screen telling you how to get rid of the annoying message.
