I'm editing a radio play and one of the characters is a heart, as in, the beating heart of another character. Does anyone know any effects I could use in Adobe Audition that I could use on the voice? The aim is to differentiate it from other voices in the play and possibly make it sound like it's coming from inside someone's body.
On a separate issue, what effect could I use to make it sound like someone's talking to themselves, in their head (i.e. to differentiate their voice from when they're having a conversation out loud).
