MediaFire is good, fast, and free. Don't know if there are any places that let you upload without an account anymore.
If the problem is introduced from a sub-optimal resampling algorithm, one of the best resamplers is open source: SoX. I don't know if incorporating it into Dolphin would be sensible, feasible, or efficient, but the idea is the only contribution this layperson can make. Maybe just a part of its code could be used or an idea gained by looking at it.
