I started using Smule 2 months back. This is the best app created by mankind for mankind. Here we can sing songs of our choice and voila! it just magically modifies our voice and makes us sound really good just like a professional playback singer. The karaoke database is really huge and I was able to find all my favourite songs in all languages. We can also sing duets with other singers and some of them sing really well. Even if we can’t sing as good as them, somehow the app is able to match our voices and the end result sounds decently good enough. This app is a must for all people who love singing. It is turn even bathroom singers sound like professional singers.
