Thanks for the feedback, Jeff. Unfortunately there are several middlemen between me and whoever is handling the audio engineering on their end so I can’t get the answers to those questions. I’ve never had a client have problems with .wav files I’ve sent before, so I’m not sure what’s different here. The client is a company that is based in Europe, but I don’t think that’s a factor here because it’s their North American division that is using the file I’m sending. Stumped.
