I recomend doing what I did and either make a "Video" on youtube or photobucket and then upload it that way. :) we dont have a way YET to upload sounds. Im working on it though :)
Yeah that is what I have found works best. Once you have your EVP cropped make it into a video and upload it to youtube or photobucket. Then you can link the videos that way. I have yet to find an audio only upload site for that sort of thing. If I ever find one I will be sure to link it. ^_^
