So, I've corrected all three sections, in Chapter 4 I did my best to make it more smooth, although it's far from perfect.
The corrected spots are:
Chapter 1 - silence at the beginning, 5:08 "grave of a lately lost child"
Chapter 4 - silence at the beginning, 0:38, 2:56 and 14:09. I didn't do anything with the "grand palace" at 5:35..
Chapter 20 - silence at the beginning
