Basically what the title says. For the past year or so, the tracks I have been uploading onto Soundcloud keep sounding bad. The original file sounds fine, but once it's uploaded, everything sounds grainy and distorted, like a low rumble going through the whole song. Earlier tracks I've uploaded do not have this problem. I don't seem to be doing anything different, so the issue doesn't appear to be on my end. What could be the problem? Can this be fixed?
