Investigating Audio Production
Sound is important, it helps us communicate and know whats going on around us. We develop the ability to hear very early in a pregnancy and can evens till hear in the womb, we can hear things like music and some people think we can even tell different voices apart.
Diegetic and Non-Diegetic sound
Diegetic sound: There are two types of Diegetic sound, external and internal, external diegetic sound is sound that can be heard by the characters like people talking or gunshots or traffic and internal diegetic sound is sound that the characters hear thats internal like the difference between being underwater and not.
Non-Diegetic sound: Non-Diegetic sound is sound that is in the film or tv show that the characters can't hear such as a sound track or a laughing audience.
Background Ambiance
Background Ambience is all of the sounds going on in the background of a scene, for example if it takes place in a city then you would hear cars and people walking past but if the scene was in a classroom there would be people chatting.
Panning
Panning is where the audio changes depending on where the camera is, for example a car alarm moving from the left side of the shot to the right side then the audio would copy that with the sound moving from let to right as well.
Sound bridges
Sound bridges are sound from the next scene that can be heard before they are scene which act as a transition between the two scenes like and alarm clock after a dream or moving from inside and hearing the sounds of a city before transitioning into a shot of the city.
Dialogue
Dialogue isn't just two people in a conversation it can also be things like a voice over where someone is narrating what is happening, most of the time it is used for conversations.
ADR
ADR (Automated Dialogue Replacement) is the process that is used to replace audio in a scene, for example if different people are doing the acting and the voice they would do this to replace the voice of the actor with the voice of the voice actor. It might also be used to cover up lines that had been mumbled to to hide inappropriate language from younger audiences.
Foley
Foley is where you use object to make sound effects like using vegetables for bonebreaking sounds or punching a book for the sound of punching. It's often used for sounds that are hard for the camera to pick up like footsteps or for actions they want to have more impact like adding punch sounds. We also did a task where we had to replicate some sounds using Foley so I made a punch sound, a snap sound and a footstep sound which I recorded with my phone.
For this task we were given a set of sounds that we had to use to make a soundscape, I used the sounds given to make a soundscape of someone walking home and I used panning to make it sound like they were walking past people talking and make the noise of a helicopter flying by. I also reversed the door opening sound so that it makes the sound of the door closing.
Fo this talk we were given the audio that goes along with the video and we had to put it together. First thing i did was add the ambiance and footsteps and hit sounds for when one of the characters gets thrown into a wall. After I added the different sound effects I used the effect part of audition to add reverb to everything as the scene takes place in a stairwell which would be quite reverberant.
For this we were shown how to use audition to make it sound like someone is speaking on the phone, for this we had two clips, one of a phone ringing and one of two people having a conversation. For this I started by cutting down the phone ringing so that it isn't very long and added a full reverb effect so that it sounds like it is in a living room, I then separated the voices so that I could have different effects in each of the voices. One of them I changed the reverb so that it sounded like they are in the same room as the phone and the other I added a FFT filter effect let me make it sound like the other voice was talking through a phone.
