This is Atom, I'm gonna give the advice this time because Elly is asleep. There are a few things going on here that need to be fixed; the first being the effect you added to Wilford's voice. It sounds like your voice changer has a weird effect that causes him to sound like he's muffled or underwater. My advice it to can the voice changer completely and edit pitch manually; Wilford only talks in a low pitch after all. There's no need for an echo of any sort. You also should remove the background noise and leftover mic noise by using the noise reduction option in wavepad. Audios need to be very, very clear in order to maintain the quality set for the group. Finally there's the accent itself; while you did a pretty darn good job it still needs to be more slurred. Wilford sounds almost as if he's inebriated when he speaks; at least in the more modern time frame of Markiplier TV, The Ned Affair, ect. All in all though it's pretty good for a first attempt and I encourage you to keep trying!
