The sound effects of Caged consisted mostly of foley sounds that I recorded myself mixed with royalty free sound effects for scenes I found difficult to make sounds for, such as explosions. The sound effects were then compiled with the film in premiere.
The enhanced sound was a definite improvement as sounds had the echo, although i reverted the bird's cough and Overlords scream to the original as the echo (which was realistic) took away from the effect that I wanted to achieve with them. So the end result was a mixture of realistic and non realistic effects to make the world believable but to also make sure the film's narrative was not harmed in the process.
Huge thanks to Joe for creating the original soundtrack and taking the sound effects to a whole new level.
