#1 In the fist corpse,  I chose the sound of a piano and a trolley. I added reverb to them in order to achieve the echoing sound effect. The sounds become softer.

#2 In the second corpse, I chose to edit the sound of a hand dryer and the sound of a hand rubbing the recorder. I shifted the pitch and adjusted the time shift in order to make them similar but somehow different. Delay and Reverb were added too. The sounds turned to be deeper and wetter.

#3 In the third corpse, I chose to use the sound of a bell and sounds from the coffee shop. In order to make the sound of the bell not to be very sharp, I added EQ and compression. And also time shift was used to adjust the speed of the sound tracks.

#4 In the fourth corpse, I used the sound of a chair moving and sound from the water pipe. I edited the sounds in pro tool so there was no chorus. Scifi was used instead. And also fade in and out.

The volume was adjusted and I used lots of fades.
