I dont know.......I listened to the whole thing, 3 tunes, and I hear a ton of some vocoder type effect that might seem kinda annoying after a while, but I didn't hear any distortion. It's a pretty hot mix, but it didn't distort for me. I thought the vox were mixed appropriately compared to the rest of the tracks. Many DIY recorders have a tendency to undermix the vox, make them too soft, but this sounded balanced to me. I like the vox to be slightly above the rest of the music, and that's what I hear in this......
