If you like Auto-Tuning, check this out. T-Pain has been using Auto-Tune so much that it’s become his trademark sound, and people have been capitalizing on this. The “I Am T-Pain Mic“ will let you sing into the microphone and it will play it back in T-Pain’s signature voice.
You can even record your singing and transfer the file to your PC if you want to. Is it worth $40? Well, I guess that depends on your taste in music.
