I've been experiencing clicks and pops on my audio tracks that I upload to SoundCloud when I stream on my computer. Sometimes the sound even drops out. These artifacts are nonexistent in the original audio files and it doesn't seem to happen when I stream on my phone... When I stream on my computer the artifacts occur at the same moment every time that the tracks are played, though sometimes the clicks/pops are longer or shorter in duration.
For example, see my track "The Place Where Rainbows Came From" and listen for the sound dropping out at approx. 39 seconds. Does it happen on your end?
All the files I am uploading are .wav format.
