Mobile DJ is essentially an MP3 player with a number of advanced features that affect audio playback. It's designed for DJs who need a way to add DSP effects, equalization and pitch shifts to their songs during sets.

To use the program, you load in an MP3, WAV or other file and press the play button in the middle of the screen. You can adjust the tempo and the pitch of the song independently. You also have considerable control over balance, volume and equalization. You can cue files, fade in and out, normalize and add in your own effects as necessary. Mobild DJ even has a microphone setting that allows you to input your own voice, instruments or other audio source to your sound file without leaving the application.

Since this is a DJ app, it's designed for live performance. This means that you cannot save your creations in the Mobile DJ program, but experienced DJs will know to feed the program through another application to record sound.

We like Mobile DJ's straightforward interface. Other DJ applications give you a tremendous amount of information at once and are often overwhelming for first-time users. This program is small, simple and easy. However, a few extra dialog boxes and visualizers would make it even easier to use.

Professional DJs will undoubtedly prefer a tool with more features, but Mobile DJ is a great purchase for anyone trying to learn more about the craft. It has an intuitive interface and works well enough thanks to the smart inclusion of a few high-quality features and effects. Overall, it's well worth a look even if you only have a passing interest in live audio mixing.
