Virtual DJ Studio 3.1

Virtual DJ Studio (VDJ) is an MP3 Mixer for live DJ performances. With it, you can Mix MP3 Files, use multiple Sound Cards, and adjust Pitch and Tempo on each file individually. VDJ also contains a full 10-band Graphic Equalizer, full support for Audio Plugins, a Spectrum Analyzer, and many more tools for DJs.
Virtual DJ Studio Main Features:

Feature-Filled DJ Software:Virtual DJ Studio is not like all of the other DJ programs out there. While other programs limit you to two players with a Cross-Fader, Virtual DJ Studio provides you with an entire studio.The two-deck metaphor is out-dated. There is no reason to limit yourself when your PC can easily give you so much more. Now, with Virtual DJ Studio, you can break free from this tired metaphor!You can select how many Lines appear on VDJs interface. You can configure as many lines as will fit on your screen.
Easy to Use:Don't be intimidated by the number of buttons you see in the picture. If you have a knack for audio equipment, you will quickly pick up on VDJs use. VDJ comes with a complete Help file, including a Getting Started guide that will have you mixing MP3s in no time!
File Navigator:VDJ3's File Navigator gives you a whole new way to locate your music. It functions as a file manager, displaying all supported file types along with extra information (bitrate, sample frequency, bit resolution, etc). The File Navigator lets you preview any file without having to open it. File Navigator also contains an integrated Playlist Editor, for building and managine PLS, M3U or VDJ playlist files.File Navigator also has two File Queues, holding areas for songs you just want to keep handy. You might use one for song requests, and the other to store common popular tunes. Both File Queues remember what they contained the next time you open VDJ.
Improved Drag 'N Drop Support:You can drag files from the File Navigator, File Queue, or any other Windows program (such as Windows Exporer or your Desktop). You can also drag files from any line in VDJ to another line, or into the File Queue (or even to other programs).VDJ3 gives you limitless possibilities with Drag 'N Drop, allowing you to intuitively open and manage files.
Headphone Support:VDJ allows you to use an extra sound card for CUEing, or Previewing, a sound file. You can use this feature to assist with beat-mixing (fading two songs together on-beat), or for simply previewing a song before playing it live.
Plugin Support:VDJ3 now offers Plugin support. Third parties can contribute audio processing plugins that can be used within VDJ3's Plugin Manager. VDJ3 comes with a few Plugins as well, including a Compressor/Limiter, a Low-Pass Filter, and Stereo Expansion.
