Want to sound like Madonna?...
A new service from Synchro Arts, better known for its professional audio work in the film industry, will take your voice and attempt to change the pitch, tone, and timing to match a wide range of popular songs.
The idea is to have a popular song reproduced with your own voice as your phone ringtone, and the technology is impressive – even more so in that it will run on a standard PC. The download is 34MB, and you'll need to register first, but then you just sing along in best karaoke fashion, and once you're done the software tries its best to make the whole thing sound sensible and in tune. It also offers to do the whole thing over the phone, but using a PC gives you more options for trying different tunes and hearing how well the system works. The resulting ringtone will set you back £1.50, though many are free as an introductory offer, and playing with the software on a PC to see how it fares is also free.
So for some Christmas afternoon silliness, nothing beats singing to your computer - just make sure you're alone when you do it!
