WEEK 14 – SOUND

Sound Terms:

Non-diegetic – sounds added on top of the scene, such as extra sound effects, music and voice-overs – the actors do not hear it while acting

Diegetic – sounds heard within the scene that are natural

Foley – recording sound with the scene in sync after

Amos – sound you record of your space

Dubbing – using previously recorded sound from one type to another

Signal – the audio you want to use and record

Noise – other audio, created by the atmosphere/equipment that you don’t want to use

Signal To Noise Ratio

Screen Shot 2014-01-06 at 10.18.46

Ratio = 1:1 = equal signal and noise

Ratio = 2-:1 = 20 times more signal than noise

Ideal – a lot more signal than noise.

Microphones

Sub-cardiod mics has a very gradually reducing sensitive from the front to the back – maintaining some sensitivity at the back

Cardiod mics has a gradually reducing sensitive from the front to the back, with very little sensitivity at the back..

Super-cardiod mics reduces the sensitivity from the front to the sides at a faster rate than carded types – minimum sensitivity at an angle from the front. Sensitivity increases, and reduces at the back.

Hyper-cardiod mics, provides even less sensitivity at the sides, a little more sensitivity at the back.

‘Rifle’ or ‘shotgun’ mics are the most directional type, they are mainly for long-distance.

Bi-directional mics pick up sound with equal sensitivity from both front and back.

Stereo mic recording requires two mics recording to two separate channels. These polar patterns overlap and are sometimes included in a single unit.

 

Sound ideas for my film: 

When the glass drops to the floor – thud

Wind howling in the background – spooky tense effect

Footsteps

Thud when stumbling around

Crunching leaves

Flashback – baby laughing/crawling

Flashback – toys rattling/squeaking

Slurping drink

Crying
