I make alot of movies (short films, and stuff). Im currenly looking at making a trailer for a film in making and want to use my voice. Does anyone know of anygood audio apps that i can use to play with the sound of my voice or other sounds. Im used to playing with video apps such as premiere but never really playied with any audio apps so it's hard to know where to start.

I know this isn't really the right question as this is a video site but i know you lot know what your talking about and im sure somone can point me in the right direction of where to start

Cheers
