Lab DJ is a mixing program for your digital music. It can be used instead of turntables and a mixer at your next party, or instead of a bunch of DJ equipment at a wedding. It also makes a great practice tool for the wannabe DJ. It supports all file types, CDs, and has many sound altering features. With Lab DJ, you can play your music faster, slower, with effects, and backwards. You can use two sound cards as well as a wealth of visual aids from Lab DJ to make you a better DJ.
