Even if you post it as a WAV, Soundcloud still converts it to a 128 bps MP3 for their standard playback. However, I believe that if you upload a lossless format, it can be downloaded at a higher quality. However, Dave, you don't seem to have allowed the track to be uploaded. I can't see any upload button. You might have to play with the track setting.
I'm hearing a lot of clicks on the track. Are they on the original or is that Soundcloud's encoding adding them?
