So I've recently finished a new track which I'm really excited about showcasing to you all. However, when I upload it to soundcloud I have a problem. In the intro as it builds up I have a nice sub bass patch, now once it's uploaded to the cloud it seems to distort. Like as if it's phasing to the left and right?????? I deleted it, went back to my DAW, checked it was in mono, which it was, lowered the volume slightly and re-uploaded........same problem. So I check in my DAW again, and everything sounds fine. Render to mp3 and play it through my PC, everythings fine, whack it on my iphone....everythings fine. Take it to a frinds house on a memory stick, play it through his monitors....guess what.......everythings fine. But as soon as I upload it to soundcloud I am hearing the same problems!!!!! Any ideas how to rectify the problem?
