Version 1.1 is finished! The old download source still works.

Update: alas, still not finished, as kk650 keeps finding new glitches. I will wait till he's done.

Some clarification at this point. The glitches indicated by kk650 are mostly inherent in the original mono sound and not the result of its synching to the 4K edition. Some of them are actually still present in the mono downmix of the 4K. I am looking into the most severe ones in order to fix them, but some is just not possible (at least for me) without introducing further artefacts.
