If you like to sing your favorite songs accompanied by the original music track, then you may enjoy this program. It lets you dim the vocal track from any song so you can overimpose your own vocals. You can save the instrumental track so you can use it later at parties with your friends.
The program is easy to use. You only need to open the desired file and adjust several controls such as level, balance, attenuation, and treble/bass boost. The program also allows you to change the key and tempo of the song according to your voice type.
I tested the program on songs from different records, and found that the default settings work pretty well in most cases, provided that the songs are in WMA, WAV or other high-quality formats. If you use a low-quality format, the results tend to be poorer, so you may want to take this into account.
The program also has options to merge different tracks into one and to extract clips from songs. You can adjust the settings of the output file.
You can use the trial version of the program a limited number of times. Also, it will process only the first minute of each song, showing a "nag screen" from time to time. If you want to get rid of all these limitations, then you will need to purchase a license.
