What does a party usually need? A DJ of course, one that can successfully improve the mood of the guests. But a karaoke machine is also a must-have, because that's where people bond over how badly they can sing. So, why not combine the two elements?
Virtual DJ Studio is the ideal software to have at parties. It supports karaoke, audio mixing, playlists, and even multiple sound cards.
Once installation finishes (which is very fast), you will probably think the user interface is pretty intimidating (especially if you're a rookie).
But anyone can use Virtual DJ Studio, regardless of their level of experience in the audio mixing environment. Just take your time to get familiarized with it.
What can you do with this application? Play several MP3 and WAV files, enable auto crossfade, and adjust tempo and pitch to match the beat. It doesn't have complex features, but everything you need for a successful musical experience.
You can configure as many lines as you wish. Each one of them has a full MP3, Wave and Playlist player, with volume fader, pitch control, tempo control, and other options.
After playing with it for a little while, you'll probably notice how practical but also fun Virtual DJ Studio is. Besides, CPU and memory are moderately used, so you probably won't have any problems in that area.
In conclusion, if you want to liven up any party, then Virtual DJ Studio is probably one of the best options you have at hand. You have plenty of time to test it, and the full version price is not that much either.
