zombie84 said (while quoting the info on the disc itself):

The main source for the 1977 mono theatrical mix came from “The Mono Mix Restoration Project” and would not have been possible here without their hard work. The track, while mostly complete, contained audio drop outs and some gaps, which were filled from a second mono source. All audio was cleaned up to minimize the optical track crackle and rumble. The original transfer was not speed locked, so varispeed and numerous edits were required to patch and slide audio back into sync.

Reading this again, I'm not sure what EditDroid are referring to in this paragraph. Are they talking about the work that Belbucus did to patch, clean up and sync the mono mix from my capture, or did they carry out further work to the audio using Belbucus' final audio as their master?
