Radiologik DJ is a sophisticated DJing application aimed mainly at professional radio DJs.
Radiologik DJ consists of three main players and one library player. All of them have customizable individual audio outputs and detailed time calculations. They also all integrate with iTunes, and a special scheduler for automating transmissions although this has to be downloaded separately.
The two program players consist of an independent voiceover player and a library player. The players operate in the same way as they would in a radio station environment by overlapping at your command. You can configure custom start and stop fades for each track played and you can search directly in iTunes from the Radiologik DJ interface. The integration with iTunes is superb with tracks imported instantly, searches lightening quick and support for dragging and dropping tracks into Radiologik DJ.
For professionals, Radiologik DJ has a lot to offer. The automatic track playing time calculations and the scheduler are two particularly useful features. However, for beginners, Radiologik DJ isn't particularly user friendly - it takes a lot of getting used to and despite the iTunes integration, isn't ideal for those just starting out.
For professional radio DJs, Radiologik DJ is a complete and highly accomplished solution.
