Thanks Guitarhacker

I do use Melodyne Editor and yes it's excellent. When I said shaky vocals I didnt mean quivering but just alittle raw sounding. Thats cause of the speakers on the mobile devices because it sounds nice on my computer. It just made me realise how different music can sound and alot of people will listen from their devices rather sat in front of some nice speakers. In fact my vocals just seemed to dominate the mix on my iphone with the music coming in distant 2nd.

All my songs at the moment are mixed on my headphones/Hi Fi until I get a pair of (probably) KRK RP8 G3.
