Sound Research

Digetic Sound
Is sound that the audience hear but also the characters such as a conversation or walking down a corridor to make it more obvious you usually get a reaction from the character  this could also be known as "Literal Sound" or "Actual Sound".


Non-digetic Sound
Is sound that is not present in the story space so you cant visibly see the source of the sound on screen and the characters don't react to the sound in any way this could also be known as "Non-literal Sound" or "Commentary Sound".


External Digetic Sound
Sound coming from a physical source within the story space which you assume all the characters can hear this could be the sound effects present in a fight scene like breaking bones.


Internal Digetic Sound
Sound coming from the mind of a character such as a small piece of dialogue talking about someone you would be able to hear and so would the character but no other characters in the room.


Stereo and Dolby Digital 5.1
Stereo is an older use of sound display which is based on having 2 audio channels left and right which usual means that there are 2 microphones picking up the sound and feeding it into the left and right speakers.
Dolby Digital 5.1 is a surround sound format and is the basic format used for audio on DVD Video Dolby Digital can have up to 5 channels compared to the Stereo's 2 channels the 5 channels are: front center, front left, front right, surround left and surround right.

Sound Clip

I am analyzing the use of sound in the short film above, i decided to watch until 1:30 then start analyzing. The first thing i notice is the use of a soundtrack for a while then the sound effects come in first with the woman opening the door i think that it was likely to be recorded on set with a zoom because it has a crisp sound and if not then it could of been recorded of set by simply opening a door or cabinet the next major sound i picked up on was the sound of the ripping which would of had to be a Foley effect recorded before the filming this could of been done by simply ripping a sheet or ripping the jeans the sound of the phone was likely recorded at a different point as well due to the volume of the ringing which i believe was edited i think the woman's dialog was recorded on set using a zoom because of the clarity of the recording and how well it fits to the visuals the mans voice was recorded at a different point and cut in again likely a quiet location with a zoom.

Overall the use of sound and sound effects gives you a comedic feel for this character and makes you feel as though nothing goes right for her.

If all the sound effects were recorded on set they might of been less clear which wouldn't of made them stand out as much but it may make you feel more immersed as though you were there. some effects had to be recorded separately like the man talking.

The sound effect i was interested in is called "Knock Knock" it is likely to be an actual recording of someone knocking rather then folly the sound was probably recorded in an empty roof hence the echo and with a microphone of decent quality such as a Zoom or a Marantz.
